XTERM(1)                                                              XTERM(1)



NAME
       xterm - terminal emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...] [shell]

DESCRIPTION
       The xterm program is a terminal emulator for the X Window System.  It
       provides DEC VT102/VT220 (VTxxx) and Tektronix 4014 compatible
       terminals for programs that cannot use the window system directly.  If
       the underlying operating system supports terminal resizing capabilities
       (for example, the SIGWINCH signal in systems derived from 4.3bsd),
       xterm will use the facilities to notify programs running in the window
       whenever it is resized.

       The VTxxx and Tektronix 4014 terminals each have their own window so
       that you can edit text in one and look at graphics in the other at the
       same time.  To maintain the correct aspect ratio (height/width),
       Tektronix graphics will be restricted to the largest box with a 4014's
       aspect ratio that will fit in the window.  This box is located in the
       upper left area of the window.

       Although both windows may be displayed at the same time, one of them is
       considered the ``active'' window for receiving keyboard input and
       terminal output.  This is the window that contains the text cursor.
       The active window can be chosen through escape sequences, the ``VT
       Options'' menu in the VTxxx window, and the ``Tek Options'' menu in the
       4014 window.

EMULATIONS
       The VT102 emulation is fairly complete, but does not support
       autorepeat.  Double-size characters are displayed properly if your font
       server supports scalable fonts.  The VT220 emulation does not support
       soft fonts, it is otherwise complete.  Termcap(5) entries that work
       with xterm include an optional platform-specific entry, ``xterm,''
       ``vt102,'' ``vt100,'' ``ansi'' and ``dumb.''  xterm automatically
       searches the termcap file in this order for these entries and then sets
       the ``TERM'' and the ``TERMCAP'' environment variables.  You may also
       use ``vt220,''  but must set the terminal emulation level with the
       decTerminalID resource.  (The ``TERMCAP'' environment variable is not
       set if xterm is linked against a terminfo library, since the requisite
       information is not provided by the termcap emulation of terminfo
       libraries).

       Many of the special xterm features may be modified under program
       control through a set of escape sequences different from the standard
       VT102 escape sequences.  (See the Xterm Control Sequences document.)

       The Tektronix 4014 emulation is also fairly good.  It supports 12-bit
       graphics addressing, scaled to the window size.  Four different font
       sizes and five different lines types are supported.  There is no
       write-through or defocused mode support.  The Tektronix text and
       graphics commands are recorded internally by xterm and may be written
       to a file by sending the COPY escape sequence (or through the Tektronix
       menu; see below).  The name of the file will be
       ``COPYyyyy-MM-dd.hh:mm:ss'', where yyyy, MM, dd, hh, mm and ss are the
       year, month, day, hour, minute and second when the COPY was performed
       (the file is created in the directory xterm is started in, or the home
       directory for a login xterm).

       Not all of the features described in this manual are necessarily
       available in this version of xterm.  Some (e.g., the non-VT220
       extensions) are available only if they were compiled in, though the
       most commonly-used are in the default configuration.

OTHER FEATURES
       Xterm automatically highlights the text cursor when the pointer enters
       the window (selected) and unhighlights it when the pointer leaves the
       window (unselected).  If the window is the focus window, then the text
       cursor is highlighted no matter where the pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an
       alternate screen buffer, which is the same size as the display area of
       the window.  When activated, the current screen is saved and replaced
       with the alternate screen.  Saving of lines scrolled off the top of the
       window is disabled until the normal screen is restored.  The termcap(5)
       entry for xterm allows the visual editor vi(1) to switch to the
       alternate screen for editing and to restore the screen on exit.  A
       popup menu entry makes it simple to switch between the normal and
       alternate screens for cut and paste.

       In either VT102 or Tektronix mode, there are escape sequences to change
       the name of the windows.  Additionally, in VT102 mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location on the screen.

       Xterm allows character-based applications to receive mouse events
       (currently button-press and release events, and button-motion events)
       as keyboard control sequences.  See Xterm Control Sequences for
       details.

OPTIONS
       The xterm terminal emulator accepts the standard X Toolkit command line
       options as well as many application-specific options.  If the option
       begins with a `+' instead of a `-', the option is restored to its
       default value.  The -version and -help options are interpreted even if
       xterm cannot open the display, and are useful for testing and
       configuration scripts:

       -version
               This causes xterm to print a version number to the standard
               output.

       -help   This causes xterm to print out a verbose message describing its
               options, one per line.  The message is written to the standard
               output.  Xterm generates this message, sorting it and noting
               whether a "-option" or a "+option" turns the feature on or off,
               since some features historically have been one or the other.
               Xterm generates a concise help message (multiple options per
               line) when an unknown option is used, e.g.,
                    xterm -z


              If the logic for a particular option such as logging is not
              compiled into xterm, the help text for that option also is not
              displayed by the -help option.

       One parameter (after all options) may be given.  That overrides xterm's
       built-in choice of shell program.  Normally xterm checks the SHELL
       variable.  If that is not set, xterm tries to use the shell program
       specified in the password file.  If that is not set, xterm uses
       /bin/sh.  If the parameter names an executable file, xterm uses that
       instead.  The parameter must be an absolute path, or name a file found
       on the user's PATH (and thereby construct an absolute path).  The -e
       option cannot be used with this parameter since it uses all parameters
       following the option.

       The other options are used to control the appearance and behavior.  Not
       all options are necessarily configured into your copy of xterm:

       -132    Normally, the VT102 DECCOLM escape sequence that switches
               between 80 and 132 column mode is ignored.  This option causes
               the DECCOLM escape sequence to be recognized, and the xterm
               window will resize appropriately.

       -ah     This option indicates that xterm should always highlight the
               text cursor.  By default, xterm will display a hollow text
               cursor whenever the focus is lost or the pointer leaves the
               window.

       +ah     This option indicates that xterm should do text cursor
               highlighting based on focus.

       -ai     This option disables active icon support if that feature was
               compiled into xterm.  This is equivalent to setting the vt100
               resource activeIcon to ``false''.

       +ai     This option enables active icon support if that feature was
               compiled into xterm.  This is equivalent to setting the vt100
               resource activeIcon to ``true''.

       -aw     This option indicates that auto-wraparound should be allowed.
               This allows the cursor to automatically wrap to the beginning
               of the next line when it is at the rightmost position of a line
               and text is output.

       +aw     This option indicates that auto-wraparound should not be
               allowed.

       -b number
               This option specifies the size of the inner border (the
               distance between the outer edge of the characters and the
               window border) in pixels.  That is the vt100 internalBorder
               resource.  The default is 2.

       +bc     turn off text cursor blinking.  This overrides the cursorBlink
               resource.

       -bc     turn on text cursor blinking.  This overrides the cursorBlink
               resource.

       -bcf milliseconds
               set the amount of time text cursor is off when blinking via the
               cursorOffTime resource.

       -bcn milliseconds
               set the amount of time text cursor is on when blinking via the
               cursorOffTime resource.

       -bdc    Set the vt100 resource colorBDMode to ``false'', disabling the
               display of characters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to ``true'', enabling the
               display of characters with bold attribute as color rather than
               bold

       -cb     Set the vt100 resource cutToBeginningOfLine to ``false''.

       +cb     Set the vt100 resource cutToBeginningOfLine to ``true''.

       -cc characterclassrange:value[,...]
               This sets classes indicated by the given ranges for using in
               selecting by words.  See the section specifying character
               classes.  and discussion of the charClass resource.

       -cjk_width
               Set the cjkWidth resource to ``true''.  When turned on,
               characters with East Asian Ambiguous (A) category in UTR 11
               have a column width of 2.  Otherwise, they have a column width
               of 1.  This may be useful for some legacy CJK text
               terminal-based programs assuming box drawings and others to
               have a column width of 2.  It also should be turned on when you
               specify a TrueType CJK double-width (bi-width/monospace) font
               either with -fa at the command line or faceName resource.  The
               default is ``false''

       +cjk_width
               Reset the cjkWidth resource.

       -class string
               This option allows you to override xterm's resource class.
               Normally it is ``XTerm'', but can be set to another class such
               as ``UXTerm'' to override selected resources.

       -cm     This option disables recognition of ANSI color-change escape
               sequences.  It sets the colorMode resource to ``false''.

       +cm     This option enables recognition of ANSI color-change escape
               sequences.  This is the same as the vt100 resource colorMode.

       -cn     This option indicates that newlines should not be cut in
               line-mode selections.  It sets the cutNewline resource to
               ``false''.

       +cn     This option indicates that newlines should be cut in line-mode
               selections.  It sets the cutNewline resource to ``true''.

       -cr color
               This option specifies the color to use for text cursor.  The
               default is to use the same foreground color that is used for
               text.  It sets the cursorColor resource according to the
               parameter.

       -cu     This option indicates that xterm should work around a bug in
               the more(1) program that causes it to incorrectly display lines
               that are exactly the width of the window and are followed by a
               line beginning with a tab (the leading tabs are not displayed).
               This option is so named because it was originally thought to be
               a bug in the curses(3x) cursor motion package.

       +cu     This option indicates that xterm should not work around the
               more(1) bug mentioned above.

       -dc     This option disables the escape sequence to change dynamic
               colors: the vt100 foreground and background colors, its text
               cursor color, the pointer cursor foreground and background
               colors, the Tektronix emulator foreground and background
               colors, its text cursor color and highlight color.  The option
               sets the dynamicColors option to ``false''.

       +dc     This option enables the escape sequence to change dynamic
               colors.  The option sets the dynamicColors option to ``true''.

       -e program [ arguments ... ]
               This option specifies the program (and its command line
               arguments) to be run in the xterm window.  It also sets the
               window title and icon name to be the basename of the program
               being executed if neither -T nor -n are given on the command
               line.  This must be the last option on the command line.

       -en encoding
               This option determines the encoding on which xterm runs.  It
               sets the locale resource.  Encodings other than UTF-8 are
               supported by using luit.  The -lc option should be used instead
               of -en for systems with locale support.

       -fb font
               This option specifies a font to be used when displaying bold
               text.  It sets the boldFont resource.


               This font must be the same height and width as the normal font,
               otherwise it is ignored.  If only one of the normal or bold
               fonts is specified, it will be used as the normal font and the
               bold font will be produced by overstriking this font.


               See also the discussion of boldMode and alwaysBoldMode
               resources.

       -fa pattern
               This option sets the pattern for fonts selected from the
               FreeType library if support for that library was compiled into
               xterm.  This corresponds to the faceName resource.  When a CJK
               double-width font is specified, you also need to turn on the
               cjkWidth resource.


               See also the renderFont resource, which combines with this to
               determine whether FreeType fonts are initially active.

       -fbb    This option indicates that xterm should compare normal and bold
               fonts bounding boxes to ensure they are compatible.  It sets
               the freeBoldBox resource to ``false''.

       +fbb    This option indicates that xterm should not compare normal and
               bold fonts bounding boxes to ensure they are compatible.  It
               sets the freeBoldBox resource to ``true''.

       -fbx    This option indicates that xterm should not assume that the
               normal and bold fonts have VT100 line-drawing characters.  If
               any are missing, xterm will draw the characters directly.  It
               sets the forceBoxChars resource to ``false''.

       +fbx    This option indicates that xterm should assume that the normal
               and bold fonts have VT100 line-drawing characters.  It sets the
               forceBoxChars resource to ``true''.

       -fd pattern
               This option sets the pattern for double-width fonts selected
               from the FreeType library if support for that library was
               compiled into xterm.  This corresponds to the
               faceNameDoublesize resource.

       -fi font
               This option sets the font for active icons if that feature was
               compiled into xterm.


               See also the discussion of the iconFont resource.

       -fs size
               This option sets the pointsize for fonts selected from the
               FreeType library if support for that library was compiled into
               xterm.  This corresponds to the faceSize resource.

       -fw font
               This option specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as wide
               as the font that will be used to draw normal text.  If no
               double-width font is found, it will improvise, by stretching
               the normal font.  This corresponds to the wideFont resource.

       -fwb font
               This option specifies the font to be used for displaying bold
               wide text.  By default, it will attempt to use a font twice as
               wide as the font that will be used to draw bold text.  If no
               double-width font is found, it will improvise, by stretching
               the bold font.  This corresponds to the wideBoldFont resource.

       -fx font
               This option specifies the font to be used for displaying the
               preedit string in the "OverTheSpot" input method.


               See also the discussion of the ximFont resource.

       -hc color
               (see -selbg).

       -hf     This option indicates that HP Function Key escape codes should
               be generated for function keys.  It sets the hpFunctionKeys
               resource to ``true''.

       +hf     This option indicates that HP Function Key escape codes should
               not be generated for function keys.  It sets the hpFunctionKeys
               resource to ``false''.

       -hm     Tells xterm to use highlightTextColor and highlightColor to
               override the reversed foreground/background colors in a
               selection.  It sets the highlightColorMode resource to
               ``true''.

       +hm     Tells xterm not to use highlightTextColor and highlightColor to
               override the reversed foreground/background colors in a
               selection.  It sets the highlightColorMode resource to
               ``false''.

       -hold   Turn on the hold resource, i.e., xterm will not immediately
               destroy its window when the shell command completes.  It will
               wait until you use the window manager to destroy/kill the
               window, or if you use the menu entries that send a signal,
               e.g., HUP or KILL.

       +hold   Turn off the hold resource, i.e., xterm will immediately
               destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the
               pseudo-terminal's sense of the stty erase value.

       +ie     Turn off the ptyInitialErase resource, i.e., set the stty erase
               value using the kb string from the termcap entry as a
               reference, if available.

       -im     Turn on the useInsertMode resource, which forces use of insert
               mode by adding appropriate entries to the TERMCAP environment
               variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
               Given an X window identifier (a decimal integer), xterm will
               reparent its top-level shell widget to that window.  This is
               used to embed xterm within other applications.

       -j      This option indicates that xterm should do jump scrolling.  It
               corresponds to the jumpScroll resource.  Normally, text is
               scrolled one line at a time; this option allows xterm to move
               multiple lines at a time so that it does not fall as far
               behind.  Its use is strongly recommended since it makes xterm
               much faster when scanning through large amounts of text.  The
               VT100 escape sequences for enabling and disabling smooth scroll
               as well as the ``VT Options'' menu can be used to turn this
               feature on or off.

       +j      This option indicates that xterm should not do jump scrolling.

       -k8     This option sets the allowC1Printable resource.  When
               allowC1Printable is set, xterm overrides the mapping of C1
               control characters (code 128-159) to treat them as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
               This option sets the keyboardType resource.  Possible values
               include: ``unknown'', ``default'', ``hp'', ``sco'', ``sun'',
               ``tcap'' and ``vt220''.


               The value ``unknown'', causes the corresponding resource to be
               ignored.


               The value ``default'', suppresses the associated resources
               hpFunctionKeys, scoFunctionKeys, sunFunctionKeys,
               tcapFunctionKeys and sunKeyboard, using the Sun/PC keyboard
               layout.

       -l      Turn logging on.  Normally logging is not supported, due to
               security concerns.  Some versions of xterm may have logging
               enabled.  The logfile is written to the directory from which
               xterm is invoked.  The filename is generated, of the form

                    XtermLog.XXXXXX

               or

                    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

               depending on how xterm was built.

       +l      Turn logging off.

       -lc     Turn on support of various encodings according to the users'
               locale setting, i.e., LC_ALL, LC_CTYPE, or LANG environment
               variables.  This is achieved by turning on UTF-8 mode and by
               invoking luit for conversion between locale encodings and
               UTF-8.  (luit is not invoked in UTF-8 locales.)  This
               corresponds to the locale resource.


               The actual list of encodings which are supported is determined
               by luit.  Consult the luit manual page for further details.


               See also the discussion of the -u8 option which supports UTF-8
               locales.

       +lc     Turn off support of automatic selection of locale encodings.
               Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
               UTF-8 mode will be used.

       -lcc path
               File name for the encoding converter from/to locale encodings
               and UTF-8 which is used with -lc option or locale resource.
               This corresponds to the localeFilter resource.

       -leftbar
               Force scrollbar to the left side of VT100 screen.  This is the
               default, unless you have set the rightScrollBar resource.

       -lf filename
               Specify the log-filename.  See the -l option.

       -ls     This option indicates that the shell that is started in the
               xterm window will be a login shell (i.e., the first character
               of argv[0] will be a dash, indicating to the shell that it
               should read the user's .login or .profile).


               The -ls flag and the loginShell resource are ignored if -e is
               also given, because xterm does not know how to make the shell
               start the given command after whatever it does when it is a
               login shell - the user's shell of choice need not be a Bourne
               shell after all.  Also, xterm -e is supposed to provide a
               consistent functionality for other applications that need to
               start text-mode programs in a window, and if loginShell were
               not ignored, the result of ~/.profile might interfere with
               that.


               If you do want the effect of -ls and -e simultaneously, you may
               get away with something like
                      xterm -e /bin/bash -l -c "my command here"


              Finally, -ls is not completely ignored, because xterm -ls -e
              does write a /etc/wtmp entry (if configured to do so), whereas
              xterm -e does not.

       -maximized
               This option indicates that xterm should ask the window manager
               to maximize its layout on startup.  This corresponds to the
               maximized resource.


               Maximizing is not the reverse of iconifying; it is possible to
               do both with certain window managers.

       +maximized
               This option indicates that xterm should ask the window manager
               to maximize its layout on startup.

       +ls     This option indicates that the shell that is started should not
               be a login shell (i.e., it will be a normal ``subshell'').

       -mb     This option indicates that xterm should ring a margin bell when
               the user types near the right end of a line.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
               This option specifies the maximum time between multi-click
               selections.

       -mesg   Turn off the messages resource, i.e., disallow write access to
               the terminal.

       +mesg   Turn on the messages resource, i.e., allow write access to the
               terminal.

       -mk_width
               Set the mkWidth resource to ``true''.  This makes xterm use a
               built-in version of the wide-character width calculation.  The
               default is ``false''

       +mk_width
               Reset the mkWidth resource.

       -ms color
               This option specifies the color to be used for the pointer
               cursor.  The default is to use the foreground color.  This sets
               the pointerColor resource.

       -nb number
               This option specifies the number of characters from the right
               end of a line at which the margin bell, if enabled, will ring.
               The default is 10.

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

       -pc     This option enables the PC-style use of bold colors (see
               boldColors resource).

       +pc     This option disables the PC-style use of bold colors.

       -pob    This option indicates that the window should be raised whenever
               a Control-G is received.

       +pob    This option indicates that the window should not be raised
               whenever a Control-G is received.

       -rightbar
               Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the display of characters with reverse
               attribute as color.

       +rvc    This option enables the display of characters with reverse
               attribute as color.

       -rw     This option indicates that reverse-wraparound should be
               allowed.  This allows the cursor to back up from the leftmost
               column of one line to the rightmost column of the previous
               line.  This is very useful for editing long shell command lines
               and is encouraged.  This option can be turned on and off from
               the ``VT Options'' menu.

       +rw     This option indicates that reverse-wraparound should not be
               allowed.

       -s      This option indicates that xterm may scroll asynchronously,
               meaning that the screen does not have to be kept completely up
               to date while scrolling.  This allows xterm to run faster when
               network latencies are very high and is typically useful when
               running across a very large internet or many gateways.

       +s      This option indicates that xterm should scroll synchronously.

       -samename
               Does not send title and icon name change requests when the
               request would have no effect: the name is not changed.  This
               has the advantage of preventing flicker and the disadvantage of
               requiring an extra round trip to the server to find out the
               previous value.  In practice this should never be a problem.

       +samename
               Always send title and icon name change requests.

       -sb     This option indicates that some number of lines that are
               scrolled off the top of the window should be saved and that a
               scrollbar should be displayed so that those lines can be
               viewed.  This option may be turned on and off from the ``VT
               Options'' menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -selbg color
               This option specifies the color to use for the background of
               selected text.  If not specified, reverse video is used.  See
               the discussion of the highlightColor resource.

       -selfg color
               This option specifies the color to use for selected text.  If
               not specified, reverse video is used.  See the discussion of
               the highlightTextColor resource.

       -sf     This option indicates that Sun Function Key escape codes should
               be generated for function keys.

       +sf     This option indicates that the standard escape codes should be
               generated for function keys.

       -si     This option indicates that output to a window should not
               automatically reposition the screen to the bottom of the
               scrolling region.  This option can be turned on and off from
               the ``VT Options'' menu.

       +si     This option indicates that output to a window should cause it
               to scroll to the bottom.

       -sk     This option indicates that pressing a key while using the
               scrollbar to review previous lines of text should cause the
               window to be repositioned automatically in the normal position
               at the bottom of the scroll region.

       +sk     This option indicates that pressing a key while using the
               scrollbar should not cause the window to be repositioned.

       -sl number
               This option specifies the number of lines to save that have
               been scrolled off the top of the screen.  This corresponds to
               the saveLines resource.  The default is 64.

       -sm     This option, corresponding to the sessionMgt resource,
               indicates that xterm should set up session manager callbacks.

       +sm     This option indicates that xterm should not set up session
               manager callbacks.

       -sp     This option indicates that Sun/PC keyboard should be assumed,
               providing mapping for keypad ``+' to ``,', and CTRL-F1 to F13,
               CTRL-F2 to F14, etc.

       +sp     This option indicates that the standard escape codes should be
               generated for keypad and function keys.

       -t      This option indicates that xterm should start in Tektronix
               mode, rather than in VT102 mode.  Switching between the two
               windows is done using the ``Options'' menus.  Termcap(5)
               entries that work with xterm ``tek4014,'' ``tek4015,''
               ``tek4012,'' ``tek4013,'' ``tek4010,'' and ``dumb.''  xterm
               automatically searches the termcap file in this order for these
               entries and then sets the ``TERM'' and the ``TERMCAP''
               environment variables.

       +t      This option indicates that xterm should start in VT102 mode.

       -tb     This option, corresponding to the toolBar resource, indicates
               that xterm should display a toolbar (or menubar) at the top of
               its window.  The buttons in the toolbar correspond to the popup
               menus, e.g., control/left/mouse for "Main Options".

       +tb     This option indicates that xterm should not set up a toolbar.

       -ti term_id
               Specify the name used by xterm to select the correct response
               to terminal ID queries.  It also specifies the emulation level,
               used to determine the type of response to a DA control
               sequence.  Valid values include vt52, vt100, vt101, vt102, and
               vt220 (the "vt" is optional).  The default is vt100.  The
               term_id argument specifies the terminal ID to use.  (This is
               the same as the decTerminalID resource).

       -tm string
               This option specifies a series of terminal setting keywords
               followed by the characters that should be bound to those
               functions, similar to the stty program.  The keywords and their
               values are described in detail in the ttyModes resource.

       -tn name
               This option specifies the name of the terminal type to be set
               in the TERM environment variable.  It corresponds to the
               termName resource.  This terminal type must exist in the
               terminal database (termcap or terminfo, depending on how xterm
               is built) and should have li# and co# entries.  If the terminal
               type is not found, xterm uses the built-in list ``xterm'',
               ``vt102'', etc.

       -u8     This option sets the utf8 resource.  When utf8 is set, xterm
               interprets incoming data as UTF-8.  This sets the wideChars
               resource as a side-effect, but the UTF-8 mode set by this
               option prevents it from being turned off.  If you must turn it
               on and off, use the wideChars resource.


               This option and the utf8 resource are overridden by the -lc and
               -en options and locale resource.  That is, if xterm has been
               compiled to support luit, and the locale resource is not
               ``false'' this option is ignored.  We recommend using the -lc
               option or the ``locale: true'' resource in UTF-8 locales when
               your operating system supports locale, or -en UTF-8 option or
               the ``locale: UTF-8'' resource when your operating system does
               not support locale.

       +u8     This option resets the utf8 resource.

       -uc     This option makes the cursor underlined instead of a box.

       +uc     This option makes the cursor a box instead of underlined.

       -ulc    This option disables the display of characters with underline
               attribute as color rather than with underlining.

       +ulc    This option enables the display of characters with underline
               attribute as color rather than with underlining.

       -ulit   This option, corresponding to the italicULMode resource,
               disables the display of characters with underline attribute as
               italics rather than with underlining.

       +ulit   This option, corresponding to the italicULMode resource,
               enables the display of characters with underline attribute as
               italics rather than with underlining.

       -ut     This option indicates that xterm should not write a record into
               the the system utmp log file.

       +ut     This option indicates that xterm should write a record into the
               system utmp log file.

       -vb     This option indicates that a visual bell is preferred over an
               audible one.  Instead of ringing the terminal bell whenever a
               Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell should not be used.

       -wc     This option sets the wideChars resource.  When wideChars is
               set, xterm maintains internal structures for 16-bit characters.
               If you do not set this resource to ``true'', xterm will ignore
               the escape sequence which turns UTF-8 mode on and off.  The
               default is ``false''.

       +wc     This option resets the wideChars resource.

       -wf     This option indicates that xterm should wait for the window to
               be mapped the first time before starting the subprocess so that
               the initial terminal size settings and environment variables
               are correct.  It is the application's responsibility to catch
               subsequent terminal size changes.

       +wf     This option indicates that xterm should not wait before
               starting the subprocess.

       -ziconbeep percent
               Same as zIconBeep resource.  If percent is non-zero, xterms
               that produce output while iconified will cause an XBell sound
               at the given volume and have "***" prepended to their icon
               titles.  Most window managers will detect this change
               immediately, showing you which window has the output.  (A
               similar feature was in x10 xterm.)

       -C      This option indicates that this window should receive console
               output.  This is not supported on all systems.  To obtain
               console output, you must be the owner of the console device,
               and you must have read and write permission for it.  If you are
               running X under xdm on the console screen you may need to have
               the session startup and reset programs explicitly change the
               ownership of the console device in order to get this option to
               work.

       -Sccn   This option allows xterm to be used as an input and output
               channel for an existing program and is sometimes used in
               specialized applications.  The option value specifies the last
               few letters of the name of a pseudo-terminal to use in slave
               mode, plus the number of the inherited file descriptor.  If the
               option contains a ``/'' character, that delimits the characters
               used for the pseudo-terminal name from the file descriptor.
               Otherwise, exactly two characters are used from the option for
               the pseudo-terminal name, the remainder is the file descriptor.
               Examples (the first two are equivalent since the descriptor
               follows the last ``/''):

                      -S/dev/pts/123/45
                      -S123/45
                      -Sab34


              Note that xterm does not close any file descriptor which it did
              not open for its own use.  It is possible (though probably not
              portable) to have an application which passes an open file
              descriptor down to xterm past the initialization or the -S
              option to a process running in the xterm.

       The following command line arguments are provided for compatibility
       with older versions.  They may not be supported in the next release as
       the X Toolkit provides standard options that accomplish the same task.

       %geom   This option specifies the preferred size and position of the
               Tektronix window.  It is shorthand for specifying the
               ``*tekGeometry'' resource.

        #geom  This option specifies the preferred position of the icon
               window.  It is shorthand for specifying the ``*iconGeometry''
               resource.

       -T string
               This option specifies the title for xterm's windows.  It is
               equivalent to -title.

       -n string
               This option specifies the icon name for xterm's windows.  It is
               shorthand for specifying the ``*iconName'' resource.  Note that
               this is not the same as the toolkit option -name (see below).
               The default icon name is the application name.

       -r      This option indicates that reverse video should be simulated by
               swapping the foreground and background colors.  It is
               equivalent to -rv.

       -w number
               This option specifies the width in pixels of the border
               surrounding the window.  It is equivalent to -borderwidth or
               -bw.

       The following standard X Toolkit command line arguments are commonly
       used with xterm:

       -bd color
               This option specifies the color to use for the border of the
               window.  The corresponding resource name is borderColor.  xterm
               uses the X Toolkit default, which is ``XtDefaultForeground''.

       -bg color
               This option specifies the color to use for the background of
               the window.  The corresponding resource name is background.
               The default is ``XtDefaultBackground.''

       -bw number
               This option specifies the width in pixels of the border
               surrounding the window.


               This appears to be a legacy of older X releases.  It sets the
               borderWidth resource of the shell widget, and may provide
               advice to your window manager to set the thickness of the
               window frame.  Most window managers do not use this
               information.  See the -b option, which controls the inner
               border of the xterm window.

       -display display
               This option specifies the X server to contact; see X(7).

       -fg color
               This option specifies the color to use for displaying text.
               The corresponding resource name is foreground.  The default is
               ``XtDefaultForeground.''

       -fn font
               This option specifies the font to be used for displaying normal
               text.  The corresponding resource name is font.  The resource
               value default is fixed.

       -font font
               This is the same as -fn.

       -geometry geometry
               This option specifies the preferred size and position of the
               VT102 window; see X(7).

       -iconic This option indicates that xterm should ask the window manager
               to start it as an icon rather than as the normal window.  The
               corresponding resource name is iconic.

       -name name
               This option specifies the application name under which
               resources are to be obtained, rather than the default
               executable file name.  Name should not contain ``.'' or ``*''
               characters.

       -rv     This option indicates that reverse video should be simulated by
               swapping the foreground and background colors.  The
               corresponding resource name is reverseVideo.

       +rv     Disable the simulation of reverse video by swapping foreground
               and background colors.

       -title string
               This option specifies the window title string, which may be
               displayed by window managers if the user so chooses.  The
               default title is the command line specified after the -e
               option, if any, otherwise the application name.

       -xrm resourcestring
               This option specifies a resource string to be used.  This is
               especially useful for setting resources that do not have
               separate command line options.

RESOURCES
       The program understands all of the core X Toolkit resource names and
       classes.  Application specific resources (e.g., "XTerm.NAME") follow:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
               Tie the VTxxx backarrowKey and ptyInitialErase resources
               together by setting the DECBKM state according to whether the
               initial value of stty erase is a backspace (8) or delete (127)
               character.  The default is ``false'', which disables this
               feature.

       hold (class Hold)
               If true, xterm will not immediately destroy its window when the
               shell command completes.  It will wait until you use the window
               manager to destroy/kill the window, or if you use the menu
               entries that send a signal, e.g., HUP or KILL.  You may scroll
               back, select text, etc., to perform most graphical operations.
               Resizing the display will lose data, however, since this
               involves interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
               Specifies whether or not HP Function Key escape codes should be
               generated for function keys instead of standard escape
               sequences.


               See also the keyboardType resource.

       iconGeometry (class IconGeometry)
               Specifies the preferred size and position of the application
               when iconified.  It is not necessarily obeyed by all window
               managers.

       iconName (class IconName)
               Specifies the icon name.  The default is the application name.

       keyboardType (class KeyboardType)
               Enables one (or none) of the various keyboard-type resources:
               hpFunctionKeys, scoFunctionKeys, sunFunctionKeys,
               tcapFunctionKeys and sunKeyboard.  The resource's value should
               be one of the corresponding strings ``hp'', ``sco'', ``sun'',
               ``tcap'' or ``vt220''.  The individual resources are provided
               for legacy support; this resource is simpler to use.

       maxBufSize (class MaxBufSize)
               Specify the maximum size of the input buffer.  The default is
               32768.  You cannot set this to a value less than the minBufSize
               resource.  It will be increased as needed to make that value
               evenly divide this one.


               On some systems you may want to increase one or both of the
               maxBufSize and minBufSize resource values to achieve better
               performance if the operating system prefers larger buffer
               sizes.

       maximized (class Maximized)
               Specifies whether or not xterm should ask the window manager to
               maximize its layout on startup.  The default is ``false.''

       messages (class Messages)
               Specifies whether write access to the terminal is allowed
               initially.  See mesg(1). The default is ``true''.

       menuLocale (class MenuLocale)
                Specify the locale used for character-set computations when
                loading the popup menus.  Use this to improve initialization
                performance of the Athena popup menus, which may load
                unnecessary (and very large) fonts, e.g., in a locale having
                UTF-8 encoding.  The default is the "C" (POSIX).


                To use the current locale (only useful if you have localized
                the resource settings for the menu entries), set the resource
                to an empty string.

       minBufSize (class MinBufSize)
               Specify the minimum size of the input buffer, i.e., the amount
               of data that xterm requests on each read.  The default is 4096.
               You cannot set this to a value less than 64.

       ptyHandshake (class PtyHandshake)
               If ``true'', xterm will perform handshaking during
               initialization to ensure that the parent and child processes
               update the utmp and stty state.


               See also waitForMap which waits for the pseudo-terminal's
               notion of the screen size, and ptySttySize which resets the
               screen size after other terminal initialization is complete.
               The default is ``true''.

       ptyInitialErase (class PtyInitialErase)
               If ``true'', xterm will use the pseudo-terminal's sense of the
               stty erase value.  If ``false'', xterm will set the stty erase
               value to match its own configuration, using the kb string from
               the termcap entry as a reference, if available.  In either
               case, the result is applied to the TERMCAP variable which xterm
               sets.


               See also the ttyModes resource, which may modify this.  The
               default is ``false''.

       ptySttySize (class PtySttySize)
               If ``true'', xterm will reset the screen size after terminal
               initialization is complete.  This is needed for some systems
               whose pseudo-terminals cannot propagate terminal
               characteristics.  Where it is not needed, it can interfere with
               other methods for setting the intial screen size, e.g., via
               window manager interaction.


               See also waitForMap which waits for a handshake-message giving
               the pseudo-terminal's notion of the screen size.  The default
               is ``false'' on Linux and OS X systems, ``true'' otherwise.

       sameName (class SameName)
               If the value of this resource is ``true'', xterm does not send
               title and icon name change requests when the request would have
               no effect: the name is not changed.  This has the advantage of
               preventing flicker and the disadvantage of requiring an extra
               round trip to the server to find out the previous value.  In
               practice this should never be a problem.  The default is
               ``true''.

       scoFunctionKeys (class ScoFunctionKeys)
               Specifies whether or not SCP Function Key escape codes should
               be generated for function keys instead of standard escape
               sequences.


               See also the keyboardType resource.

       sessionMgt (class SessionMgt)
               If the value of this resource is ``true'', xterm sets up
               session manager callbacks for XtNdieCallback and
               XtNsaveCallback.  The default is ``true''.

       sunFunctionKeys (class SunFunctionKeys)
               Specifies whether or not Sun Function Key escape codes should
               be generated for function keys instead of standard escape
               sequences.


               See also the keyboardType resource.

       sunKeyboard (class SunKeyboard)
               Specifies whether or not Sun/PC keyboard layout should be
               assumed rather than DEC VT220.  This causes the keypad ``+' to
               be mapped to ``,'.  and CTRL F1-F12 to F11-F20, depending on
               the setting of the ctrlFKeys resource.  so xterm emulates a DEC
               VT220 more accurately.  Otherwise (the default, with
               sunKeyboard set to ``false''), xterm uses PC-style bindings for
               the function keys and keypad.


               PC-style bindings use the Shift, Alt, Control and Meta keys as
               modifiers for function-keys and keypad (see the document Xterm
               Control Sequences for details).  The PC-style bindings are
               analogous to PCTerm, but not the same thing.  Normally these
               bindings do not conflict with the use of the Meta key as
               described for the eightBitInput resource.  If they do, note
               that the PC-style bindings are evaluated first.


               See also the keyboardType resource.

       tcapFunctionKeys (class TcapFunctionKeys)
               Specifies whether or not function key escape codes read from
               the termcap/terminfo entry should be generated for function
               keys instead of standard escape sequences.


               See also the keyboardType resource.

       termName (class TermName)
               Specifies the terminal type name to be set in the TERM
               environment variable.

       title (class Title)
               Specifies a string that may be used by the window manager when
               displaying this application.

       toolBar (class ToolBar)
               Specifies whether or not the toolbar should be displayed.  The
               default is ``true.''

       ttyModes (class TtyModes)
               Specifies a string containing terminal setting keywords and the
               characters to which they may be bound.  Allowable keywords
               include: brk, dsusp, eof, eol, eol2, erase, erase2, flush,
               intr, kill, lnext, quit, rprnt, start, status, stop, susp,
               swtch and weras.  Control characters may be specified as ^char
               (e.g., ^c or ^u) and ^? may be used to indicate delete (127).
               Use ^- to denote undef.  Use \034 to represent ^\, since a
               literal backslash in an X resource escapes the next character.


               This is very useful for overriding the default terminal
               settings without having to do an stty every time an xterm is
               started.  Note, however, that the stty program on a given host
               may use different keywords; xterm's table is built-in.


               If the ttyModes resource specifies a value for erase, that
               overrides the ptyInitialErase resource setting, i.e., xterm
               initializes the terminal to match that value.

       useInsertMode (class UseInsertMode)
               Force use of insert mode by adding appropriate entries to the
               TERMCAP environment variable.  This is useful if the system
               termcap is broken.  The default is ``false.''

       utmpDisplayId (class UtmpDisplayId)
               Specifies whether or not xterm should try to record the display
               identifier (display number and screen number) as well as the
               hostname in the system utmp log file.  The default is ``true.''

       utmpInhibit (class UtmpInhibit)
               Specifies whether or not xterm should try to record the user's
               terminal in the system utmp log file.  If true, xterm will not
               try.  The default is ``false.''

       waitForMap (class WaitForMap)
               Specifies whether or not xterm should wait for the initial
               window map before starting the subprocess.  This is part of the
               ptyHandshake logic.  When xterm is directed to wait in this
               fashion, it passes the terminal size from the display end of
               the pseudo-terminal to the terminal I/O connection, e.g.,
               according to the window manager.  Otherwise, it uses the size
               as given in resource values or command-line option -geom.  The
               default is ``false.''

       zIconBeep (class ZIconBeep)
               Same as -ziconbeep command line argument.  If the value of this
               resource is non-zero, xterms that produce output while
               iconified will cause an XBell sound at the given volume and
               have "***" prepended to their icon titles.  Most window
               managers will detect this change immediately, showing you which
               window has the output.  (A similar feature was in x10 xterm.)
               The default is ``false.''

   VT100 Widget Resources
       The following resources are specified as part of the vt100 widget
       (class VT100).  They are specified by patterns such as
       "XTerm.vt100.NAME".

       If your xterm is configured to support the "toolbar", then those
       patterns need an extra level for the form-widget which holds the
       toolbar and vt100 widget.  A wildcard between the top-level "XTerm" and
       the "vt100" widget makes the resource settings work for either, e.g.,
       "XTerm*vt100.NAME".

       activeIcon (class ActiveIcon)
               Specifies whether or not active icon windows are to be used
               when the xterm window is iconified, if this feature is compiled
               into xterm.  The active icon is a miniature representation of
               the content of the window and will update as the content
               changes.  Not all window managers necessarily support
               application icon windows.  Some window managers will allow you
               to enter keystrokes into the active icon window.  The default
               is ``false.''

       allowC1Printable (class AllowC1Printable)
               If true, overrides the mapping of C1 controls (codes 128-159)
               to make them be treated as if they were printable characters.
               Although this corresponds to no particular standard, some users
               insist it is a VT100.  The default is ``false.''

       allowColorOps (class AllowColorOps)
               Specifies whether control sequences that set/query the dynamic
               colors should be allowed.  ANSI colors are unaffected by this
               resource setting.  The default is ``true.''

       allowFontOps (class AllowFontOps)
               Specifies whether control sequences that set/query the font
               should be allowed.  The default is ``true.''

       allowScrollLock (class AllowScrollLock)
               Specifies whether control sequences that set/query the Scroll
               Lock key should be allowed, as well as whether the Scroll Lock
               key responds to user's keypress.  The default is ``false.''


               When this feature is enabled, xterm will sense the state of the
               Scroll Lock key each time it acquires focus.  Pressing the
               Scroll Lock key toggles xterm's internal state, as well as
               toggling the associated LED.  While the Scroll Lock is active,
               xterm attempts to keep a viewport on the same set of lines.  If
               the current viewport is scrolled past the limit set by the
               saveLines resource, then Scroll Lock has no further effect.


               The reason for setting the default to ``false.'' is to avoid
               user surprise.  This key is generally unused in keyboard
               configurations, and has not acquired a standard meaning even
               when it is used in that manner.  Consequently, users have
               assigned it for ad hoc purposes.

       allowSendEvents (class AllowSendEvents)
               Specifies whether or not synthetic key and button events
               (generated using the X protocol SendEvent request) should be
               interpreted or discarded.  The default is ``false'' meaning
               they are discarded.  Note that allowing such events would
               create a very large security hole, therefore enabling this
               resource forcefully disables the allowXXXOps resources.  The
               default is ``false.''

       allowTcapOps (class AllowTcapOps)
               Specifies whether control sequences that query the terminal's
               notion of its function-key strings, as termcap or terminfo
               capabilities should be allowed.  The default is ``false.''


               A few programs, e.g,. vim, use this feature to get an accurate
               description of the terminal's capabilities, independent of the
               termcap/terminfo setting:
               -  xterm can tell the querying program how many colors it
                  supports.  This is a constant, depending on how it is
                  compiled, typically 16.  It does not change if you alter
                  resource settings, e.g., the boldColors resource.

               -  xterm can tell the querying program what strings are sent by
                  modified (shift-, control-, alt-) function- and keypad-keys.
                  Reporting control- and alt-modifiers is a feature that
                  relies on the ncurses extended naming.

       allowTitleOps (class AllowTitleOps)
              Specifies whether control sequences that modify the window title
              or icon name should be allowed.  The default is ``true.''

       allowWindowOps (class AllowWindowOps)
              Specifies whether extended window control sequences (as used in
              dtterm) should be allowed.  These include several control
              sequences which manipulate the window size or position, as well
              as reporting these values and the title or icon name.  Each of
              these can be abused in a script; curiously enough most terminal
              emulators that implement these restrict only a small part of the
              repertoire.  For fine-tuning, see disallowedWindowOps.  The
              default is ``false.''

       altIsNotMeta (class AltIsNotMeta)
               If ``true'', treat the Alt-key as if it were the Meta-key.
               Your keyboard may happen to be configured so they are the same.
               But if they are not, this allows you to use the same prefix-
               and shifting operations with the Alt-key as with the Meta-key.
               See altSendsEscape and metaSendsEscape.  The default is
               ``false.''

       altSendsEscape (class AltSendsEscape)
               This is an additional keyboard operation that may be processed
               after the logic for metaSendsEscape.  It is only available if
               the altIsNotMeta resource is set.


               If ``true'', Alt characters (a character combined with the
               modifier associated with left/right Alt-keys) are converted
               into a two-character sequence with the character itself
               preceded by ESC.  This applies as well to function key control
               sequences, unless xterm sees that Alt is used in your key
               translations.  If ``false'', Alt characters input from the
               keyboard cause a shift to 8-bit characters (just like
               metaSendsEscape).  By combining the Alt- and Meta-modifiers,
               you can create corresponding combinations of ESC-prefix and
               8-bit characters.  The default is ``false.''

       alwaysBoldMode (class AlwaysBoldMode)
               Specifies whether xterm should check if the normal and bold
               fonts are distinct before deciding whether to use overstriking
               to simulate bold fonts.  If this resource is true, xterm does
               not make the check for distinct fonts when deciding how to
               handle the boldMode resource.  The default is ``false.''

               boldMode   alwaysBoldMode   Comparison   Action
               ----------------------------------------------------
               false      false            ignored      use font
               false      true             ignored      use font
               true       false            same         overstrike
               true       false            different    use font
               true       true             ignored      overstrike

       alwaysHighlight (class AlwaysHighlight)
               Specifies whether or not xterm should always display a
               highlighted text cursor.  By default (if this resource is
               false), a hollow text cursor is displayed whenever the pointer
               moves out of the window or the window loses the input focus.
               The default is ``false.''

       alwaysUseMods (class AlwaysUseMods)
               Override the numLock resource, telling xterm to use the Alt and
               Meta modifiers to construct parameters for function key
               sequences even if those modifiers appear in the translations
               resource.  Normally xterm checks if Alt or Meta is used in a
               translation that would conflict with function key modifiers,
               and will ignore these modifiers in that special case.  The
               default is ``false.''

       answerbackString (class AnswerbackString)
               Specifies the string that xterm sends in response to an ENQ
               (control/E) character from the host.  The default is a blank
               string, i.e., ``''.  A hardware VT100 implements this feature
               as a setup option.

       appcursorDefault (class AppcursorDefault)
               If ``true,'' the cursor keys are initially in application mode.
               This is the same as the VT102 private DECCKM mode, The default
               is ``false.''

       appkeypadDefault (class AppkeypadDefault)
               If ``true,'' the keypad keys are initially in application mode.
               The default is ``false.''

       autoWrap (class AutoWrap)
               Specifies whether or not auto-wraparound should be enabled.
               This is the same as the VT102 DECAWM.  The default is ``true.''

       awaitInput (class AwaitInput)
               Specifies whether or not the xterm uses a 50 millisecond
               timeout to await input (i.e., to support the Xaw3d arrow
               scrollbar).  The default is ``false.''

       backarrowKey (class BackarrowKey)
               Specifies whether the backarrow key transmits a backspace (8)
               or delete (127) character.  This corresponds to the DECBKM
               control sequence.  The default (backspace) is ``true.''
               Pressing the control key toggles this behavior.

       background (class Background)
               Specifies the color to use for the background of the window.
               The default is ``XtDefaultBackground.''

       bellIsUrgent (class BellIsUrgent)
               Specifies whether to set the Urgency hint for the window
               manager when making a bell sound.  The default is ``false.''

       bellOnReset (class BellOnReset)
               Specifies whether to sound a bell when doing a hard reset.  The
               default is ``true.''

       bellSuppressTime (class BellSuppressTime)
               Number of milliseconds after a bell command is sent during
               which additional bells will be suppressed.  Default is 200.  If
               set non-zero, additional bells will also be suppressed until
               the server reports that processing of the first bell has been
               completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
               Specifies whether to combine bold attribute with colors like
               the IBM PC, i.e., map colors 0 through 7 to colors 8 through
               15.  These normally are the brighter versions of the first 8
               colors, hence bold.  The default is ``true.''

       boldFont (class BoldFont)
               Specifies the name of the bold font to use instead of
               overstriking.  There is no default for this resource.


               This font must be the same height and width as the normal font,
               otherwise it is ignored.  If only one of the normal or bold
               fonts is specified, it will be used as the normal font and the
               bold font will be produced by overstriking this font.


               See also the discussion of boldMode and alwaysBoldMode
               resources.

       boldMode (class BoldMode)
               This specifies whether or not text with the bold attribute
               should be overstruck to simulate bold fonts if the resolved
               bold font is the same as the normal font.  It may be desirable
               to disable bold fonts when color is being used for the bold
               attribute.


               Note that xterm has one bold font which you may set explicitly.
               Xterm attempts to derive a bold font for the other font
               selections (font1 through font6).  If it cannot find a bold
               font, it will use the normal font.  In each case (whether the
               explicit resource or the derived font), if the normal and bold
               fonts are distinct, this resource has no effect.  The default
               is ``true.''


               See the alwaysBoldMode resource which can modify the behavior
               of this resource.


               Although xterm attempts to derive a bold font for other font
               selections, the font server may not cooperate.  Since X11R6,
               bitmap fonts have been scaled.  The font server claims to
               provide the bold font that xterm requests, but the result is
               not always readable.  XFree86 provides a feature which can be
               used to suppress the scaling.  In the X server's configuration
               file (e.g., "/etc/X11/XFree86"), you can add ":unscaled" to the
               end of the directory specification for the "misc" fonts, which
               comprise the fixed-pitch fonts that are used by xterm.  For
               example
                    FontPath  "/usr/lib/X11/fonts/misc/"


              would become
                   FontPath  "/usr/lib/X11/fonts/misc/:unscaled"


              Depending on your configuration, the font server may have its
              own configuration file.  The same ":unscaled" can be added to
              its configuration file at the end of the directory specification
              for "misc".


              The bitmap scaling feature is also used by xterm to implement
              VT102 double-width and double-height characters.

       brokenLinuxOSC (class BrokenLinuxOSC)
               If true, xterm applies a workaround to ignore malformed control
               sequences that a Linux script might send.  Compare the palette
               control sequences documented in console_codes with ECMA-48.
               The default is ``true.''

       brokenSelections (class BrokenSelections)
               If true, xterm in 8-bit mode will interpret STRING selections
               as carrying text in the current locale's encoding.  Normally
               STRING selections carry ISO-8859-1 encoded text.  Setting this
               resource to ``true'' violates the ICCCM; it may, however, be
               useful for interacting with some broken X clients.  The default
               is ``false.''

       brokenStringTerm (class BrokenStringTerm)
               provides a work-around for some ISDN routers which start an
               application control string without completing it.  Set this to
               ``true'' if xterm appears to freeze when connecting.  The
               default is ``false.''


               Xterm's state parser recognizes several types of control
               strings which can contain text, e.g.,

               APC (Application Program Command),
               DCS (Device Control String),
               OSC (Operating System Command),
               PM (Privacy Message), and
               SOS (Start of String),


              Each should end with a string-terminator (a special character
              which cannot appear in these strings).  Ordinary control
              characters found within the string are not ignored; they are
              processed without interfering with the process of accumulating
              the control string's content.  Xterm recognizes these controls
              in all modes, although some of the functions may be suppressed
              after parsing the control.


              When enabled, this feature allows the user to exit from an
              unterminated control string when any of these ordinary control
              characters are found:

              control/D (used as an end of file in many shells),
              control/H (backspace),
              control/I (tab-feed),
              control/J (line feed aka newline),
              control/K (vertical tab),
              control/L (form feed),
              control/M (carriage return),
              control/N (shift-out),
              control/O (shift-in),
              control/Q (XOFF),
              control/X (cancel)

       c132 (class C132)
               Specifies whether or not the VT102 DECCOLM escape sequence,
               used to switch between 80 and 132 columns, should be honored.
               The default is ``false.''

       cacheDoublesize (class CacheDoublesize)
               Tells whether to cache double-sized fonts by xterm.  Set this
               to zero to disable double-sized fonts altogether.

       charClass (class CharClass)
               Specifies comma-separated lists of character class bindings of
               the form [low-]high:value.  These are used in determining which
               sets of characters should be treated the same when doing cut
               and paste.  See the CHARACTER CLASSES section.

       cjkWidth (class CjkWidth)
               Specifies whether xterm should follow the traditional East
               Asian width convention.  When turned on, characters with East
               Asian Ambiguous (A) category in UTR 11 have a column width of
               2.  You may have to set this option to ``true'' if you have
               some old East Asian terminal based programs that assume that
               line-drawing characters have a column width of 2.  If this
               resource is false, the mkWidth resource controls the choice
               between the system's wcwidth and xterm's built-in tables.  The
               default is ``false.''

       color0 (class Color0)
               

       color1 (class Color1)
               

       color2 (class Color2)
               

       color3 (class Color3)
               

       color4 (class Color4)
               

       color5 (class Color5)
               

       color6 (class Color6)
               

       color7 (class Color7)
               These specify the colors for the ISO-6429 extension.  The
               defaults are, respectively, black, red3, green3, yellow3, a
               customizable dark blue, magenta3, cyan3, and gray90.  The
               default shades of color are chosen to allow the colors 8-15 to
               be used as brighter versions.

       color8 (class Color8)
               

       color9 (class Color9)
               

       color10 (class Color10)
               

       color11 (class Color11)
               

       color12 (class Color12)
               

       color13 (class Color13)
               

       color14 (class Color14)
               

       color15 (class Color15)
               These specify the colors for the ISO-6429 extension if the bold
               attribute is also enabled.  The default resource values are
               respectively, gray30, red, green, yellow, a customizable light
               blue, magenta, cyan, and white.

       color16 (class Color16)
               

       through 

       color255 (class Color255)
               These specify the colors for the 256-color extension.  The
               default resource values are for colors 16 through 231 to make a
               6x6x6 color cube, and colors 232 through 255 to make a
               grayscale ramp.


               Resources past color15 are available as a compile-time option.
               Due to a hardcoded limit in the X libraries on the total number
               of resources (to 400), the resources for 256-colors are omitted
               when wide-character support and luit are enabled.  Besides
               inconsistent behavior if only part of the resources were
               allowed, determining the exact cutoff is difficult, and the X
               libraries tend to crash if the number of resources exceeds the
               limit.  The color palette is still initialized to the same
               default values, and can be modified via control sequences.


               On the other hand, the resource limit does permit including the
               entire range for 88-colors.

       colorAttrMode (class ColorAttrMode)
               Specifies whether colorBD, colorBL, colorRV, and colorUL should
               override ANSI colors.  If not, these are displayed only when no
               ANSI colors have been set for the corresponding position.  The
               default is ``false.''

       colorBD (class ColorBD)
               This specifies the color to use to display bold characters if
               the ``colorBDMode'' resource is enabled.  The default is
               ``XtDefaultForeground.''

       colorBDMode (class ColorAttrMode)
               Specifies whether characters with the bold attribute should be
               displayed in color or as bold characters.  Note that setting
               colorMode off disables all colors, including bold.  The default
               is ``false.''

       colorBL (class ColorBL)
               This specifies the color to use to display blink characters if
               the ``colorBLMode'' resource is enabled.  The default is
               ``XtDefaultForeground.''

       colorBLMode (class ColorAttrMode)
               Specifies whether characters with the blink attribute should be
               displayed in color.  Note that setting colorMode off disables
               all colors, including this.  The default is ``false.''

       colorMode (class ColorMode)
               Specifies whether or not recognition of ANSI (ISO-6429) color
               change escape sequences should be enabled.  The default is
               ``true.''

       colorRV (class ColorRV)
               This specifies the color to use to display reverse characters
               if the ``colorRVMode'' resource is enabled.  The default is
               ``XtDefaultForeground.''

       colorRVMode (class ColorAttrMode)
               Specifies whether characters with the reverse attribute should
               be displayed in color.  Note that setting colorMode off
               disables all colors, including this.  The default is ``false.''

       colorUL (class ColorUL)
               This specifies the color to use to display underlined
               characters if the ``colorULMode'' resource is enabled.  The
               default is ``XtDefaultForeground.''

       colorULMode (class ColorAttrMode)
               Specifies whether characters with the underline attribute
               should be displayed in color or as underlined characters.  Note
               that setting colorMode off disables all colors, including
               underlining.  The default is ``false.''

       combiningChars (class CombiningChars)
               Specifies the number of wide-characters which can be stored in
               a cell to overstrike (combine) with the base character of the
               cell.  This can be set to values in the range 0 to 4.  The
               default is ``2''.

       ctrlFKeys (class CtrlFKeys)
               In VT220 keyboard mode (see sunKeyboard resource), specifies
               the amount by which to shift F1-F12 given a control modifier
               (CTRL).  This allows you to generate key symbols for F10-F20 on
               a Sun/PC keyboard.  The default is ``10'', which means that
               CTRL F1 generates the key symbol for F11.

       curses (class Curses)
               Specifies whether or not the last column bug in more(1) should
               be worked around.  See the -cu option for details.  The default
               is ``false.''

       cursorBlink (class CursorBlink)
               Specifies whether to make the cursor blink.  The default is
               ``false.''

       cursorColor (class CursorColor)
               Specifies the color to use for the text cursor.  The default is
               ``XtDefaultForeground.''  By default, xterm attempts to keep
               this color from being the same as the background color, since
               it draws the cursor by filling the background of a text cell.
               The same restriction applies to control sequences which may
               change this color.


               Setting this resource overrides most of xterm's adjustments to
               cursor color.  It will still use reverse-video to disallow some
               cases, such as a black cursor on a black background.

       cursorOffTime (class CursorOffTime)
               Specifies the duration of the "off" part of the cursor blink
               cycle-time in milliseconds.  The same timer is used for text
               blinking.  The default is 300.

       cursorOnTime (class CursorOnTime)
               Specifies the duration of the "on" part of the cursor blink
               cycle-time, in milliseconds.  The same timer is used for text
               blinking.  The default is 600.

       cutNewline (class CutNewline)
               If ``false'', triple clicking to select a line does not include
               the Newline at the end of the line.  If ``true'', the Newline
               is selected.  The default is ``true.''

       cursorUnderLine (class CursorUnderLine)
               Specifies whether to make the cursor underlined or a box.  The
               default is ``false.''

       cutToBeginningOfLine (class CutToBeginningOfLine)
               If ``false'', triple clicking to select a line selects only
               from the current word forward.  If ``true'', the entire line is
               selected.  The default is ``true.''

       decTerminalID (class DecTerminalID)
               Specifies the emulation level (100=VT100, 220=VT220, etc.),
               used to determine the type of response to a DA control
               sequence.  Leading non-digit characters are ignored, e.g.,
               "vt100" and "100" are the same.  The default is 100.

       defaultString (class DefaultString)
               Specify the character (or string) which xterm will substitute
               when pasted text includes a character which cannot be
               represented in the current encoding.  For instance, pasting
               UTF-8 text into a display of ISO-8859-1 characters will only be
               able to display codes 0-255, while UTF-8 text can include
               Unicode values above 255.  The default is ``#'' (a single pound
               sign).


               If the undisplayable text would be double-width, xterm will add
               a space after the ``#'' character, to give roughly the same
               layout on the screen as the original text.

       deleteIsDEL (class DeleteIsDEL)
               Specifies whether the Delete key on the editing keypad should
               send DEL (127) or the VT220-style Remove escape sequence.  The
               default is ``false,'' for the latter.

       disallowedColorOps (class DisallowedColorOps)
               Specify which features will be disabled if allowColorOps is
               false.  This is a comma-separated list of names.  The default
               value is
               SetColor,GetColor,GetAnsiColor


              The names are listed below.  xterm ignores capitalization, but
              they are shown in mixed-case for clarity.
              SetColor
                   Set a specific dynamic color.

              GetColor
                   Report the current setting of a given dynamic color.

              GetAnsiColor
                   Report the current setting of a given ANSI color (actually
                   any of the colors set via ANSI-style controls).

       disallowedFontOps (class DisallowedFontOps)
               Specify which features will be disabled if allowFontOps is
               false.  This is a comma-separated list of names.  The default
               value is
               SetFont,GetFont


              The names are listed below.  xterm ignores capitalization, but
              they are shown in mixed-case for clarity.
              SetFont
                   Set the specified font.

              GetFont
                   Report the specified font.

       disallowedTcapOps (class DisallowedTcapOps)
               Specify which features will be disabled if allowTcapOps is
               false.  This is a comma-separated list of names.  The default
               value is
               SetTcap,GetTcap


              The names are listed below.  xterm ignores capitalization, but
              they are shown in mixed-case for clarity.
              SetTcap
                   (not implemented)

              GetTcap
                   Report specified function- and other special keys.

       disallowedWindowOps (class DisallowedWindowOps)
               Specify which features will be disabled if allowWindowOps is
               false.  This is a comma-separated list of names, or (for the
               controls adapted from dtterm the operation number).  The
               default value is
               20,21,SetXprop,SetSelection


              The names are listed below.  xterm ignores capitalization, but
              they are shown in mixed-case for clarity.  Where a number can be
              used as an alternative, it is given in parentheses after the
              name.
              GetIconTitle (20)
                   Report xterm window's icon label as a string.

              GetScreenSizeChars (19)
                   Report the size of the screen in characters as numbers.

              GetSelection
                   Report selection data as a base64 string.

              GetWinPosition (13)

              GetWinTitle (21)
                   Report xterm window's title as a string.

              LowerWin (6)
                   Lower the xterm window to the bottom of the stacking order.

              MaximizeWin (9)
                   Maximize window (i.e., resize to screen size).

              MinimizeWin (2)
                   Iconify window.

              PopTitle (23)
                   Pop title from internal stack.

              PushTitle (22)
                   Push title to internal stack.

              RaiseWin (5)

              RefreshWin (7)
                   Refresh the xterm window.

              RestoreWin (1)
                   De-iconify window.

              SetSelection
                   Set selection data.

              SetWinLines
                   Resize to a given number of lines, at least 24.

              SetWinPosition (3)
                   Move window to given coordinates.

              SetWinSizePixels (4)
                   Resize the xterm window to given size in pixels.

              SetXprop
                   Set X property on top-level window.

       dynamicColors (class DynamicColors)
               Specifies whether or not escape sequences to change colors
               assigned to different attributes are recognized.

       eightBitControl (class EightBitControl)
               Specifies whether or not control sequences sent by the terminal
               should be eight-bit characters or escape sequences.  The
               default is ``false.''

       eightBitInput (class EightBitInput)
               If ``true'', Meta characters (a single-byte character combined
               with the Meta modifier key) input from the keyboard are
               presented as a single character with the eighth bit turned on.
               The terminal is put into 8-bit mode.  If ``false'', Meta
               characters are converted into a two-character sequence with the
               character itself preceded by ESC.  On startup, xterm tries to
               put the terminal into 7-bit mode.  The metaSendsEscape and
               altSendsEscape resources may override this.  The default is
               ``true.''


               Generally keyboards do not have a key labeled "Meta", but "Alt"
               keys are common, and they are conventionally used for "Meta".
               If they were synonymous, it would have been reasonable to name
               this resource "altSendsEscape", reversing its sense.  For more
               background on this, see the meta function in curses.


               Note that the Alt key is not necessarily the same as the Meta
               modifier.  xmodmap lists your key modifiers.  X defines
               modifiers for shift, (caps) lock and control, as well as 5
               additional modifiers which are generally used to configure key
               modifiers.  xterm inspects the same information to find the
               modifier associated with either Meta key (left or right), and
               uses that key as the Meta modifier.  It also looks for the
               NumLock key, to recognize the modifier which is associated with
               that.


               If your xmodmap configuration uses the same keycodes for Alt-
               and Meta-keys, xterm will only see the Alt-key definitions,
               since those are tested before Meta-keys.  NumLock is tested
               first.  It is important to keep these keys distinct; otherwise
               some of xterm's functionality is not available.

       eightBitOutput (class EightBitOutput)
               Specifies whether or not eight-bit characters sent from the
               host should be accepted as is or stripped when printed.  The
               default is ``true,'' which means that they are accepted as is.

       eightBitSelectTypes (class EightBitSelectTypes)
               Override xterm's default selection target list (see
               SELECT/PASTE) for selections in normal (ISO-8859-1) mode.  The
               default is an empty string, which does not override anything.

       faceName (class FaceName)
               Specify the pattern for fonts selected from the FreeType
               library if support for that library was compiled into xterm.
               There is no default value.


               If not specified, or if there is no match for both normal and
               bold fonts, xterm uses the font and related resources.

       faceNameDoublesize (class FaceNameDoublesize)
               Specify an double-width font for cases where an application
               requires this, e.g., in CJK applications.  There is no default
               value.


               If the application uses double-wide characters and this
               resource is not given, xterm will use a scaled version of the
               font given by faceName.

       faceSize (class FaceSize)
               Specify the pointsize for fonts selected from the FreeType
               library if support for that library was compiled into xterm.
               The default is ``14.''  On the VT Fonts menu, this corresponds
               to the Default entry.


               Although the default is ``14.'', this may not be the same as
               the pointsize for the default bitmap font, i.e., that assigned
               with the -fn option, or the font resource.  For example, the
               "fixed" font usually has a pointsize of ``8.''.  If you set
               faceSize to match the size of the bitmap font, then switching
               between bitmap and TrueType fonts via the font menu will give
               comparable sizes for the window.


               You can specify the pointsize for TrueType fonts selected with
               the other size-related menu entries such as Medium, Huge, etc.,
               by using one of the following resource values.  If you do not
               specify a value, they default to ``0.0'', which causes xterm to
               use the ratio of font sizes from the corresponding bitmap font
               resources to obtain a TrueType pointsize.


               If all of the faceSize resources are set, then xterm will use
               this information to determine the next smaller/larger TrueType
               font for the larger-vt-font() and smaller-vt-font() actions.
               If any are not set, xterm will use only the areas of the bitmap
               fonts.

       faceSize1 (class FaceSize1)
               Specifies the pointsize of the first alternative font.

       faceSize2 (class FaceSize2)
               Specifies the pointsize of the second alternative font.

       faceSize3 (class FaceSize3)
               Specifies the pointsize of the third alternative font.

       faceSize4 (class FaceSize4)
               Specifies the pointsize of the fourth alternative font.

       faceSize5 (class FaceSize5)
               Specifies the pointsize of the fifth alternative font.

       faceSize6 (class FaceSize6)
               Specifies the pointsize of the sixth alternative font.

       font (class Font)
               Specifies the name of the normal font.  The default is
               ``fixed.''


               See the discussion of the locale resource, which describes how
               this font may be overridden.


               NOTE: some resource files use patterns such as
               *font: fixed


              which are overly broad, affecting both
              xterm.vt100.font


              and
              xterm.vt100.utf8fonts.font


              which is probably not what you intended.

       fastScroll (class FastScroll)
               Modifies the effect of jump scroll (jumpScroll) by suppressing
               screen refreshes for the special case when output to the screen
               has completely shifted the contents off-screen.  For instance,
               cat'ing a large file to the screen does this.

       font1 (class Font1)
               Specifies the name of the first alternative font.

       font2 (class Font2)
               Specifies the name of the second alternative font.

       font3 (class Font3)
               Specifies the name of the third alternative font.

       font4 (class Font4)
               Specifies the name of the fourth alternative font.

       font5 (class Font5)
               Specifies the name of the fifth alternative font.

       font6 (class Font6)
               Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
               Specifies whether xterm should attempt to use font scaling to
               draw double-sized characters.  Some older font servers cannot
               do this properly, will return misleading font metrics.  The
               default is ``true''.  If disabled, xterm will simulate
               double-sized characters by drawing normal characters with
               spaces between them.

       fontWarnings (class FontWarnings)
               Specify whether xterm should report an error if it fails to
               load a font:
               0    Never report an error (though the X libraries may).

               1    Report an error if the font name was given as a resource
                    setting.

               2    Always report an error on failure to load a font.

       forceBoxChars (class ForceBoxChars)
               Specifies whether xterm should assume the normal and bold fonts
               have VT100 line-drawing characters:
               -    The fixed-pitch ISO-8859-*-encoded fonts used by xterm
                    normally have the VT100 line-drawing glyphs in cells 1-31.
                    Other fixed-pitch fonts may be more attractive, but lack
                    these glyphs.

               -    When using an ISO-10646-1 font and the wideChars resource
                    is true, xterm uses the Unicode glyphs which match the
                    VT100 line-drawing glyphs.


              If ``false'', xterm checks for missing glyphs in the font and
              makes line-drawing characters directly as needed.  If ``true'',
              xterm assumes the font does not contain the line-drawing
              characters, and draws them directly.  The default is ``false.''

       forcePackedFont (class ForcePackedFont)
               Specifies whether xterm should use the maximum or minimum glyph
               width when displaying using a bitmap font.  Use the maximum
               width to help with proportional fonts.  The default is
               ``true,'' denoting the minimum width.

       foreground (class Foreground)
               Specifies the color to use for displaying text in the window.
               Setting the class name instead of the instance name is an easy
               way to have everything that would normally appear in the text
               color change color.  The default is ``XtDefaultForeground.''

       formatOtherKeys (class FormatOtherKeys)
               Overrides the format of the escape sequence used to report
               modified keys with the modifyOtherKeys resource.
               0  send modified keys as parameters for function-key 27
                  (default).

               1  send modified keys as parameters for CSI u.

       freeBoldBox (class FreeBoldBox)
               Specifies whether xterm should assume the bounding boxes for
               normal and bold fonts are compatible.  If ``false'', xterm
               compares them and will reject choices of bold fonts that do not
               match the size of the normal font.  The default is ``false'',
               which means that the comparison is performed.

       geometry (class Geometry)
               Specifies the preferred size and position of the VT102 window.
               There is no default for this resource.

       highlightColor (class HighlightColor)
               Specifies the color to use for the background of selected
               (highlighted) text.  If not specified (i.e., matching the
               default foreground), reverse video is used.  The default is
               ``XtDefaultForeground.''

       highlightColorMode (class HighlightColorMode)
               Specifies whether xterm should use highlightTextColor and
               highlightColor to override the reversed foreground/background
               colors in a selection.  The default is unspecified: at startup,
               xterm checks if those resources are set to something other than
               the default foreground and background colors.  Setting this
               resource disables the check.


               The following table shows the interaction of the highlighting
               resources, abbreviated as shown to fit in this page:
               HCM
                  highlightColorMode

               HR highlightReverse

               HBG

       highlightReverse (class HighlightReverse)
               Specifies whether xterm should reverse the selection foreground
               and background colors when selecting text with reverse-video
               attribute.  This applies only to the highlightColor and
               highlightTextColor resources, e.g., to match the color scheme
               of xwsh.  If ``true'', xterm reverses the colors, If ``false'',
               xterm does not reverse colors, The default is ``true.''

       highlightSelection (class HighlightSelection)
               If ``false'', selecting with the mouse highlights all positions
               on the screen between the beginning of the selection and the
               current position.  If ``true'', xterm highlights only the
               positions that contain text that can be selected.  The default
               is ``false.''


               Depending on the way your applications write to the screen,
               there may be trailing blanks on a line.  Xterm stores data as
               it is shown on the screen.  Erasing the display changes the
               internal state of each cell so it is not considered a blank for
               the purpose of selection.  Blanks written since the last erase
               are selectable.  If you do not wish to have trailing blanks in
               a selection, use the trimSelection resource.

       highlightTextColor (class HighlightTextColor)
               Specifies the color to use for the foreground of selected
               (highlighted) text.  If not specified (i.e., matching the
               default background), reverse video is used.  The default is
               ``XtDefaultBackground.''

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
               Specifies whether to work around a bug in HP's xdb, which
               ignores termcap and always sends ESC F to move to the lower
               left corner.  ``true'' causes xterm to interpret ESC F as a
               request to move to the lower left corner of the screen.  The
               default is ``false.''

       i18nSelections (class I18nSelections)
               If false, xterm will not request the targets COMPOUND_TEXT or
               TEXT. The default is ``true.'' It may be set to false in order
               to work around ICCCM violations by other X clients.

       iconBorderColor (class BorderColor)
               Specifies the border color for the active icon window if this
               feature is compiled into xterm.  Not all window managers will
               make the icon border visible.

       iconBorderWidth (class BorderWidth)
               Specifies the border width for the active icon window if this
               feature is compiled into xterm.  The default is 2.  Not all
               window managers will make the border visible.

       iconFont (class IconFont)
               Specifies the font for the miniature active icon window, if
               this feature is compiled into xterm.  The default is "nil2".

       initialFont (class InitialFont)
               Specifies which of the VT100 fonts to use initially.  Values
               are the same as for the set-vt-font action.  The default is
               ``d'', i.e., "default".

       inputMethod (class XtCInputMethod)
               Tells xterm which type of input method to use.  There is no
               default method.

       internalBorder (class BorderWidth)
               Specifies the number of pixels between the characters and the
               window border.  The default is 2.

       italicULMode (class ColorAttrMode)
               Specifies whether characters with the underline attribute
               should be displayed in an italic font or as underlined
               characters.  It is implemented only for TrueType fonts.

       jumpScroll (class JumpScroll)
               Specifies whether or not jump scroll should be used.  This
               corresponds to the VT102 DECSCLM private mode.  The default is
               ``true.''  See fastScroll for a variation.

       keepSelection (class KeepSelection)
               Specifies whether xterm will keep the selection even after the
               selected area was touched by some output to the terminal.  The
               default is ``true''.

       keyboardDialect (class KeyboardDialect)
               Specifies the initial keyboard dialect, as well as the default
               value when the terminal is reset.  The value given is the same
               as the final character in the control sequences which change
               character sets.  The default is ``B'', which corresponds to US
               ASCII.

       nameKeymap (class NameKeymap)
               See the discussion of the keymap() action.

       limitResize (class LimitResize)
               Limits resizing of the screen via control sequence to a given
               multiple of the display dimensions.  The default is ``1''.

       locale (class Locale)
               Specifies how to use luit, an encoding converter between UTF-8
               and locale encodings.  The resource value (ignoring case) may
               be:
               true
                   xterm will use the encoding specified by the users'
                   LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables)
                   as far as possible.  This is realized by always enabling
                   UTF-8 mode and invoking luit in non-UTF-8 locales.

               medium
                   xterm will follow users' LC_CTYPE locale only for UTF-8,
                   east Asian, and Thai locales, where the encodings were not
                   supported by conventional 8bit mode with changing fonts.
                   For other locales, xterm will use conventional 8bit mode.

               checkfont
                   If mini-luit is compiled-in, xterm will check if a Unicode
                   font has been specified.  If so, it checks if the character
                   encoding for the current locale is POSIX, Latin-1 or
                   Latin-9, uses the appropriate mapping to support those with
                   the Unicode font.  For other encodings, xterm assumes that
                   UTF-8 encoding is required.

               false
                   xterm will use conventional 8bit mode or UTF-8 mode
                   according to utf8 resource or -u8 option.


              Any other value, e.g., ``UTF-8'' or ``ISO8859-2'', is assumed to
              be an encoding name; luit will be invoked to support the
              encoding.  The actual list of supported encodings depends on
              luit.  The default is ``medium''.


              Regardless of your locale and encoding, you need an ISO-10646-1
              font to display the result.  Your configuration may not include
              this font, or locale-support by xterm may not be needed.  At
              startup, xterm uses a mechanism equivalent to the
              load-vt-fonts(utf8Fonts, Utf8Fonts) action to load font name
              subresources of the VT100 widget.  That is, resource patterns
              such as "*vt100.utf8Fonts.font" will be loaded, and (if this
              resource is enabled), override the normal fonts.  If no
              subresources are found, the normal fonts such as "*vt100.font",
              etc., are used.  The resource files distributed with xterm use
              ISO-10646-1 fonts, but do not rely on them unless you are using
              the locale mechanism.

       localeFilter (class LocaleFilter)
               Specifies the file name for the encoding converter from/to
               locale encodings and UTF-8 which is used with the -lc option or
               locale resource.  The help message shown by ``xterm -help''
               lists the default value, which depends on your system
               configuration.


               If the encoding converter requires command-line parameters, you
               should put those within a shell script to execute the
               converter, and set this resource to point to the shell script.

       loginShell (class LoginShell)
               Specifies whether or not the shell to be run in the window
               should be started as a login shell.  The default is ``false.''

       marginBell (class MarginBell)
               Specifies whether or not the bell should be rung when the user
               types near the right margin.  The default is ``false.''

       metaSendsEscape (class MetaSendsEscape)
               If ``true'', Meta characters (a character combined with the
               Meta modifier key) are converted into a two-character sequence
               with the character itself preceded by ESC.  This applies as
               well to function key control sequences, unless xterm sees that
               Meta is used in your key translations.  If ``false'', Meta
               characters input from the keyboard are handled according to the
               eightBitInput resource.  The default is ``false.''

       mkSamplePass (class MkSamplePass)
               If mkSampleSize is nonzero, and mkWidth (and cjkWidth) are
               false, on startup xterm compares its built-in tables to the
               system's wide character width data to decide if it will use the
               system's data.  It tests the first mkSampleSize character
               values, and allows up to mkSamplePass mismatches before the
               test fails.  The default (for the allowed number of mismatches)
               is 256.

       mkSampleSize (class MkSampleSize)
               With mkSamplePass, this specifies a startup test used for
               initializing wide character width calculations.  The default
               (number of characters to check) is 1024.

       mkWidth (class MkWidth)
               Specifies whether xterm should use a built-in version of the
               wide character width calculation.  See also the cjkWidth
               resource which can override this.  The default is ``false.''


               Here is a summary of the resources which control the choice of
               wide character width calculation:

               cjkWidth   mkWidth   Action
               ---------------------------------------------------------------
               false      false     use system tables subject to mkSamplePass
               false      true      use built-in tables
               true       false     use built-in CJK tables
               true       true      use built-in CJK tables

       modifyCursorKeys (class ModifyCursorKeys)
               Tells how to handle the special case where Control-, Shift-,
               Alt- or Meta-modifiers are used to add a parameter to the
               escape sequence returned by a cursor-key.  The default is
               ``2'':


               Set it to -1 to disable it.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
               it would otherwise be the first.
               Set it to 3 to mark the sequence with a ``>'' to hint that it
               is private.

       modifyFunctionKeys (class ModifyFunctionKeys)
               Tells how to handle the special case where Control-, Shift-,
               Alt- or Meta-modifiers are used to add a parameter to the
               escape sequence returned by a (numbered) function-key.  The
               default is ``2''.  The resource values are similar to
               modifyCursorKeys:


               Set it to -1 to permit the user to use shift- and
               control-modifiers to construct function-key strings using the
               normal encoding scheme.
               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter if
               it would otherwise be the first.
               Set it to 3 to mark the sequence with a ``>'' to hint that it
               is private.


               If modifyFunctionKeys is zero, xterm uses Control- and
               Shift-modifiers to allow the user to construct numbered
               function-keys beyond the set provided by the keyboard:
               Control
                    adds the value given by the ctrlFKeys resource.

               Shift
                    adds twice the value given by the ctrlFKeys resource.

               Control/Shift
                    adds three times the value given by the ctrlFKeys
                    resource.


              As a special case, legacy (when oldFunctionKeys is true) or
              vt220 (when sunKeyboard is true) keyboards interpret only the
              Control-modifier when constructing numbered function-keys.  This
              is done to provide compatible keyboards for DEC VT220 and
              related terminals that implement user-defined keys (UDK).

       modifyOtherKeys (class ModifyOtherKeys)
               Like modifyCursorKeys, tells xterm to construct an escape
               sequence for other keys (such as "2") when modified by
               Control-, Alt- or Meta-modifiers.  This feature does not apply
               to function keys and well-defined keys such as ESC or the
               control keys.  The default is ``0'':
               0    disables this feature.

               1    enables this feature for keys except for those with
                    well-known behavior, e.g., Tab, Backarrow and some special
                    control character cases, e.g., Control-Space to make a
                    NUL.

               2    enables this feature for keys including the exceptions
                    listed.

       multiClickTime (class MultiClickTime)
               Specifies the maximum time in milliseconds between multi-click
               select events.  The default is 250 milliseconds.

       multiScroll (class MultiScroll)
               Specifies whether or not scrolling should be done
               asynchronously.  The default is ``false.''

       nMarginBell (class Column)
               Specifies the number of characters from the right margin at
               which the margin bell should be rung, when enabled by the
               marginBell resource.  The default is 10.

       numLock (class NumLock)
               If ``true'', xterm checks if NumLock is used as a modifier (see
               xmodmap(1)).  If so, this modifier is used to simplify the
               logic when implementing special NumLock for the sunKeyboard
               resource.  Also (when sunKeyboard is false), similar logic is
               used to find the modifier associated with the left and right
               Alt keys.  The default is ``true.''

       oldXtermFKeys (class OldXtermFKeys)
               If ``true'', xterm will use old-style control sequences for
               function keys F1 to F4, for compatibility with X Consortium
               xterm.  Otherwise, it uses the VT100-style codes for PF1 to
               PF4.  The default is ``false.''

       on2Clicks (class On2Clicks)
               

       on3Clicks (class On3Clicks)
               

       on4Clicks (class On4Clicks)
               

       on5Clicks (class On5Clicks)
               Specify selection behavior in response to multiple mouse
               clicks.  A single mouse click is always interpreted as
               described in the SELECTION section (see POINTER USAGE).
               Multiple mouse clicks (using the button which activates the
               select-start action) are interpreted according to the resource
               values of on2Clicks, etc.  The resource value can be one of
               these:
               word
                  Select a ``word'' as determined by the charClass resource.
                  See the CHARACTER CLASSES section.

               line
                  Select a line (counting wrapping).

               group
                  Select a group of adjacent lines (counting wrapping).  The
                  selection stops on a blank line, and does not extend outside
                  the current page.

               page
                  Select all visible lines, i.e., the page.

               all
                  Select all lines, i.e., including the saved lines.

               regex
                  Select a ``word'' as determined by the regular expression
                  which follows in the resource value.

               none
                  No selection action is associated with this resource.  xterm
                  interprets it as the end of the list.  For example, you may
                  use it to disable triple (and higher) clicking by setting
                  on3Clicks to ``none''.


              The default values for on2Clicks and on3Clicks are ``word'' and
              ``line'', respectively.  There is no default value for on4Clicks
              or on5Clicks, making those inactive.  On startup, xterm
              determines the maximum number of clicks by the onXClicks
              resource values which are set.

       openIm (class XtCOpenIm)
               Tells xterm whether to open the input method at startup.  The
               default is ``true''.

       pointerColor (class PointerColor)
               Specifies the foreground color of the pointer.  The default is
               ``XtDefaultForeground.''

       pointerColorBackground (class PointerColorBackground)
               Specifies the background color of the pointer.  The default is
               ``XtDefaultBackground.''

       pointerMode (class PointerMode)
               Specifies when the pointer may be hidden as the user types.  It
               will be redisplayed if the user moves the mouse, or clicks one
               of its buttons.
               0  never.  This is the default.

               1  the application running in xterm has not activated mouse
                  mode.

               2  always.

       pointerShape (class Cursor)
               Specifies the name of the shape of the pointer.  The default is
               ``xterm.''

       popOnBell (class PopOnBell)
               Specifies whether the window would be raised when Control-G is
               received.  The default is ``false.''


               If the window is iconified, this has no effect.  However, the
               zIconBeep resource provides you with the ability to see which
               iconified windows have sounded a bell.

       preeditType (class XtCPreeditType)
               Tells xterm which types of preedit (preconversion) string to
               display.  The default is ``OverTheSpot,Root''.

       printAttributes (class PrintAttributes)
               Specifies whether to print graphic attributes along with the
               text.  A real DEC VTxxx terminal will print the underline,
               highlighting codes but your printer may not handle these.  A
               ``0'' disables the attributes.  A ``1'' prints the normal set
               of attributes (bold, underline, inverse and blink) as
               VT100-style control sequences.  A ``2'' prints ANSI color
               attributes as well.  The default is ``1.''

       printerAutoClose (class PrinterAutoClose)
               If ``true'', xterm will close the printer (a pipe) when the
               application switches the printer offline with a Media Copy
               command.  The default is ``false.''

       printerCommand (class PrinterCommand)
               Specifies a shell command to which xterm will open a pipe when
               the first MC (Media Copy) command is initiated.  The default is
               a blank string.  If the resource value is given as a blank
               string, the printer is disabled.

       printerControlMode (class PrinterControlMode)
               Specifies the printer control mode.  A ``1'' selects autoprint
               mode, which causes xterm to print a line from the screen when
               you move the cursor off that line with a line feed, form feed
               or vertical tab character, or an autowrap occurs.  Autoprint
               mode is overridden by printer controller mode (a ``2''), which
               causes all of the output to be directed to the printer.  The
               default is ``0.''

       printerExtent (class PrinterExtent)
               Controls whether a print page function will print the entire
               page (true), or only the the portion within the scrolling
               margins (false).  The default is ``false.''

       printerFormFeed (class PrinterFormFeed)
               Controls whether a form feed is sent to the printer at the end
               of a print page function.  The default is ``false.''

       printerNewLine (class PrinterNewLine)
               Controls whether a newline is sent to the printer at the end of
               a print page function.  The default is ``true.''

       quietGrab (class QuietGrab)
               Controls whether the cursor is repainted when NotifyGrab and
               NotifyUngrab event types are received during change of focus.
               The default is ``false.''

       renderFont (class RenderFont)
               If xterm is built with the Xft library, this controls whether
               the faceName resource is used.  The default is ``default.''


               The resource values are strings, evaluated as booleans after
               startup.
               false
                    
                    disable the feature and use the normal (bitmap) font.

               true 
                    startup using the TrueType font specified by the faceName
                    and faceSize resource settings.  If there is no value for
                    faceName, disable the feature and use the normal (bitmap)
                    font.


                    After startup, you can still switch to/from the bitmap
                    font using the ``TrueType Fonts'' menu entry.

               default
                    
                    startup using the normal (bitmap) font, but enable the
                    ``TrueType Fonts'' menu entry to allow runtime switching
                    to/from TrueType fonts.


                    If there is no faceName resource set, then runtime
                    switching to TrueType fonts is disabled.  Xterm has a
                    separate  compiled-in value for faceName for the special
                    case where renderFont is ``default''.  That is normally
                    ``mono''.

       resizeGravity (class ResizeGravity)
               Affects the behavior when the window is resized to be taller or
               shorter.  NorthWest specifies that the top line of text on the
               screen stay fixed.  If the window is made shorter, lines are
               dropped from the bottom; if the window is made taller, blank
               lines are added at the bottom.  This is compatible with the
               behavior in R4.  SouthWest (the default) specifies that the
               bottom line of text on the screen stay fixed.  If the window is
               made taller, additional saved lines will be scrolled down onto
               the screen; if the window is made shorter, lines will be
               scrolled off the top of the screen, and the top saved lines
               will be dropped.

       retryInputMethod (class XtCRetryInputMethod)
               Tells xterm how many times to retry, in case the input-method
               server is not responding.  This is a different issue than
               unsupported preedit type, etc.  You may encounter retries if
               your X configuration (and its libraries) are missing pieces.
               Setting this resource to zero ``0'' will cancel the retrying.
               The default is ``3''.

       reverseVideo (class ReverseVideo)
               Specifies whether or not reverse video should be simulated.
               The default is ``false.''

       reverseWrap (class ReverseWrap)
               Specifies whether or not reverse-wraparound should be enabled.
               This corresponds to xterm's private mode 45.  The default is
               ``false.''

       rightScrollBar (class RightScrollBar)
               Specifies whether or not the scrollbar should be displayed on
               the right rather than the left.  The default is ``false.''

       saveLines (class SaveLines)
               Specifies the number of lines to save beyond the top of the
               screen when a scrollbar is turned on.  The default is 64.

       scrollBar (class ScrollBar)
               Specifies whether or not the scrollbar should be displayed.
               The default is ``false.''

       scrollBarBorder (class ScrollBarBorder)
               Specifies the width of the scrollbar border.  Note that this is
               drawn to overlap the border of the xterm window.  Modifying the
               scrollbar's border affects only the line between the VT100
               widget and the scrollbar.  The default value is 1.

       scrollKey (class ScrollCond)
               Specifies whether or not pressing a key should automatically
               cause the scrollbar to go to the bottom of the scrolling
               region.  This corresponds to xterm's private mode 1011.  The
               default is ``false.''

       scrollLines (class ScrollLines)
               Specifies the number of lines that the scroll-back and
               scroll-forw actions should use as a default.  The default value
               is 1.

       scrollTtyOutput (class ScrollCond)
               Specifies whether or not output to the terminal should
               automatically cause the scrollbar to go to the bottom of the
               scrolling region.  The default is ``true.''

       selectToClipboard (class SelectToClipboard)
               Tells xterm whether to use the PRIMARY or CLIPBOARD for SELECT
               tokens in the selection mechanism.  The set-select action can
               change this at runtime, allowing the user to work with programs
               that handle only one of these mechanisms.  The default is
               ``false'', which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
               Specifies whether to enable the actions larger-vt-font() and
               smaller-vt-font(), which are normally bound to the shifted
               KP_Add and KP_Subtract.  The default is ``true.''

       showBlinkAsBold (class ShowBlinkAsBold)
               Tells xterm whether to display text with blink-attribute the
               same as bold.  If xterm has not been configured to support
               blinking text, the default is ``true.'', which corresponds to
               older versions of xterm, otherwise the default is ``false.''

       showMissingGlyphs (class ShowMissingGlyphs)
               Tells xterm whether to display a box outlining places where a
               character has been used that the font does not represent.  The
               default is ``false.''

       showWrapMarks (class ShowWrapMarks)
               For debugging xterm and applications that may manipulate the
               wrapped-line flag by writing text at the right margin, show a
               mark on the right inner-border of the window.  The mark shows
               which lines have the flag set.

       signalInhibit (class SignalInhibit)
               Specifies whether or not the entries in the ``Main Options''
               menu for sending signals to xterm should be disallowed.  The
               default is ``false.''

       tekGeometry (class Geometry)
               Specifies the preferred size and position of the Tektronix
               window.  There is no default for this resource.

       tekInhibit (class TekInhibit)
               Specifies whether or not the escape sequence to enter Tektronix
               mode should be ignored.  The default is ``false.''

       tekSmall (class TekSmall)
               Specifies whether or not the Tektronix mode window should start
               in its smallest size if no explicit geometry is given.  This is
               useful when running xterm on displays with small screens.  The
               default is ``false.''

       tekStartup (class TekStartup)
               Specifies whether or not xterm should start up in Tektronix
               mode.  The default is ``false.''

       tiXtraScroll (class TiXtraScroll)
               Specifies whether xterm should scroll to a new page when
               processing the ti termcap entry, i.e., the private modes 47,
               1047 or 1049.  This is only in effect if titeInhibit is
               ``true'', because the intent of this option is to provide a
               picture of the full-screen application's display on the
               scrollback without wiping out the text that would be shown
               before the application was initialized.  The default for this
               resource is ``false.''

       titeInhibit (class TiteInhibit)
               Specifies whether or not xterm should remove ti and te termcap
               entries (used to switch between alternate screens on startup of
               many screen-oriented programs) from the TERMCAP string.  If
               set, xterm also ignores the escape sequence to switch to the
               alternate screen.  Xterm supports terminfo in a different way,
               supporting composite control sequences (also known as private
               modes) 1047, 1048 and 1049 which have the same effect as the
               original 47 control sequence.  The default for this resource is
               ``false.''

       titleModes (class TitleModes)
               Tells xterm whether to accept or return window- and icon-labels
               in ISO-8859-1 (the default) or UTF-8.  Either can be encoded in
               hexadecimal.  The default for this resource is ``0.''


               Each bit (bit "0" is 1, bit "1" is 2, etc) corresponds to one
               of the parameters set by the title modes control sequence:
               0    Set window/icon labels using hexadecimal

               1    Query window/icon labels using hexadecimal

               2    Set window/icon labels using UTF-8 (overrides utf8Titles
                    resource).

               3    Query window/icon labels using UTF-8

       translations (class Translations)
               Specifies the key and button bindings for menus, selections,
               ``programmed strings,'' etc.  The translations resource, which
               provides much of xterm's configurability, is a feature of the X
               Toolkit Intrinsics library (Xt).  See the ACTIONS section.

       trimSelection (class TrimSelection)
               If you set highlightSelection, you can see the text which is
               selected, including any trailing spaces.  Clearing the screen
               (or a line) resets it to a state containing no spaces.  Some
               lines may contain trailing spaces when an application writes
               them to the screen.  However, you may not wish to paste lines
               with trailing spaces.  If this resource is true, xterm will
               trim trailing spaces from text which is selected.  It does not
               affect spaces which result in a wrapped line, nor will it trim
               the trailing newline from your selection.  The default is
               ``false.''

       underLine (class UnderLine)
               This specifies whether or not text with the underline attribute
               should be underlined.  It may be desirable to disable
               underlining when color is being used for the underline
               attribute.  The default is ``true.''

       useClipping (class UseClipping)
               Tell xterm whether to use clipping to keep from producing dots
               outside the text drawing area.  Originally used to work around
               for overstriking effects, this is also needed to work with some
               incorrectly-sized fonts.  The default is ``true.''

       utf8 (class Utf8)
               This specifies whether xterm will run in UTF-8 mode.  If you
               set this resource, xterm also sets the wideChars resource as a
               side-effect.  The resource is an integer, expected to range
               from 0 to 3:
               0  UTF-8 mode is initially off.  The command-line option +u8
                  sets the resource to this value.  Escape sequences for
                  turning UTF-8 mode on/off are allowed.

               1  UTF-8 mode is initially on.  Escape sequences for turning
                  UTF-8 mode on/off are allowed.

               2  The command-line option -u8 sets the resource to this value.
                  Escape sequences for turning UTF-8 mode on/off are ignored.

               3  This is the default value of the resource.  It is changed
                  during initialization depending on whether the locale
                  resource was set, to 0 or 2.  See the locale resource for
                  additional discussion of non-UTF-8 locales.


              If you want to set the value of utf8, it should be in this
              range.  Other nonzero values are treated the same as ``1'',
              i.e., UTF-8 mode is initially on, and escape sequences for
              turning UTF-8 mode on/off are allowed.

       utf8Fonts (class Utf8Fonts)
               See the discussion of the locale resource.

       utf8Latin1 (class Utf8Latin1)
               If true, allow an ISO-8859-1 normal font to be combined with an
               ISO-10646 font if the latter is given via the -fw option or its
               corresponding resource value.  The default is ``false.''

       utf8SelectTypes (class Utf8SelectTypes)
               Override xterm's default selection target list (see
               SELECT/PASTE) for selections in wide-character (UTF-8) mode.
               The default is an empty string, which does not override
               anything.

       utf8Title (class Utf8Title)
               Applications can set xterm's title by writing a control
               sequence.  Normally this control sequence follows the VT220
               convention, which encodes the string in ISO-8859-1 and allows
               for an 8-bit string terminator.  If xterm is started in a UTF-8
               locale, it translates the ISO-8859-1 string to UTF-8 to work
               with the X libraries which assume the string is UTF-8.


               However, some users may wish to write a title string encoded in
               UTF-8.  Set this resource to ``true'' to allow UTF-8 encoded
               title strings.  That cancels the translation to UTF-8, allowing
               UTF-8 strings to be displayed as is.


               This feature is available as a menu entry, since it is related
               to the particular applications you are running within xterm.
               You can also use a control sequence (see the discussion of
               "Title Modes" in the control sequences document), to set an
               equivalent flag.  The titleModes resource sets the same value,
               which overrides this resource.


               The default is ``false.''

       veryBoldColors (class VeryBoldColors)
               Specifies whether to combine video attributes with colors
               specified by colorBD, colorBL, colorRV and colorUL.  The
               resource value is the sum of values for each attribute:
                 1 for reverse,
                 2 for underline,
                 4 for bold and
                 8 for blink.


              The default is ``0.''

       visualBell (class VisualBell)
               Specifies whether or not a visible bell (i.e., flashing) should
               be used instead of an audible bell when Control-G is received.
               The default is ``false.''

       visualBellDelay (class VisualBellDelay)
               Number of milliseconds to delay when displaying a visual bell.
               Default is 100.  If set to zero, no visual bell is displayed.
               This is useful for very slow displays, e.g., an LCD display on
               a laptop.

       vt100Graphics (class VT100Graphics)
               This specifies whether xterm will interpret VT100 graphic
               character escape sequences while in UTF-8 mode.  The default is
               ``true'', to provide support for various legacy applications.

       wideBoldFont (class WideBoldFont)
               This option specifies the font to be used for displaying bold
               wide text.  By default, it will attempt to use a font twice as
               wide as the font that will be used to draw bold text.  If no
               double-width font is found, it will improvise, by stretching
               the bold font.

       wideChars (class WideChars)
               Specifies if xterm should respond to control sequences that
               process 16-bit characters.  The default is ``false.''

       wideFont (class WideFont)
               This option specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as wide
               as the font that will be used to draw normal text.  If no
               double-width font is found, it will improvise, by stretching
               the normal font.

       ximFont (class XimFont)
               This option specifies the font to be used for displaying the
               preedit string in the "OverTheSpot" input method.


               In "OverTheSpot" preedit type, the preedit (preconversion)
               string is displayed at the position of the cursor.  It is the
               XIM server's responsibility to display the preedit string.  The
               XIM client must inform the XIM server of the cursor position.
               For best results, the preedit string must be displayed with a
               proper font.  Therefore, xterm informs the XIM server of the
               proper font.  The font is be supplied by a "fontset", whose
               default value is "*".  This matches every font, the X library
               automatically chooses fonts with proper charsets.  The ximFont
               resource is provided to override this default font setting.

               terminating characters, ``CRonly,'' which sends CR, and
               ``CR&EOT,'' which sends both CR and EOT.  The default is
               ``none.''

   Scrollbar Resources
       The following resources are useful when specified for the Athena
       Scrollbar widget:

       thickness (class Thickness)
               Specifies the width in pixels of the scrollbar.

       background (class Background)
               Specifies the color to use for the background of the scrollbar.

       foreground (class Foreground)
               Specifies the color to use for the foreground of the scrollbar.
               The ``thumb'' of the scrollbar is a simple checkerboard pattern
               alternating pixels for foreground and background color.

POINTER USAGE
       Once the VT102 window is created, xterm allows you to select text and
       copy it within the same or other windows.

   SELECTION
       The selection functions are invoked when the pointer buttons are used
       with no modifiers, and when they are used with the ``shift'' key.  The
       assignment of the functions described below to keys and buttons may be
       changed through the resource database; see ACTIONS below.

       Pointer button one (usually left) is used to save text into the cut
       buffer.  Move the cursor to beginning of the text, and then hold the
       button down while moving the cursor to the end of the region and
       releasing the button.  The selected text is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.  Normally (but see the discussion of on2Clicks, etc):
              -  Double-clicking selects by words.

              -  Triple-clicking selects by lines.

              -  Quadruple-clicking goes back to characters, etc.

       Multiple-click is determined by the time from button up to button down,
       so you can change the selection unit in the middle of a selection.
       Logical words and lines selected by double- or triple-clicking may wrap
       across more than one screen line if lines were wrapped by xterm itself
       rather than by the application running in the window.  If the
       key/button bindings specify that an X selection is to be made, xterm
       will leave the selected text highlighted for as long as it is the
       selection owner.

       Pointer button two (usually middle) ``types'' (pastes) the text from
       the PRIMARY selection, if any, otherwise from the cut buffer, inserting
       it as keyboard input.

       Pointer button three (usually right) extends the current selection.
       (Without loss of generality, you can swap ``right'' and ``left''
       everywhere in the rest of this paragraph.)  If pressed while closer to
       the right edge of the selection than the left, it extends/contracts the
       right edge of the selection.  If you contract the selection past the
       left edge of the selection, xterm assumes you really meant the left
       edge, restores the original selection, then extends/contracts the left
       edge of the selection.  Extension starts in the selection unit mode
       that the last selection or extension was performed in; you can
       multiple-click to cycle through them.

       By cutting and pasting pieces of text without trailing new lines, you
       can take text from several places in different windows and form a
       command to the shell, for example, or take output from a program and
       insert it into your favorite editor.  Since cut buffers are globally
       shared among different applications, you may regard each as a ``file''
       whose contents you know.  The terminal emulator and other text programs
       should be treating it as if it were a text file, i.e., the text is
       delimited by new lines.

   SCROLLING
       The scroll region displays the position and amount of text currently
       showing in the window (highlighted) relative to the amount of text
       actually saved.  As more text is saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking button one with the pointer in the scroll region moves the
       adjacent line to the top of the display window.

       Clicking button three moves the top line of the display window down to
       the pointer position.

       Clicking button two moves the display to a position in the saved text
       that corresponds to the pointer's position in the scrollbar.

   TEKTRONIX POINTER
       Unlike the VT102 window, the Tektronix window does not allow the
       copying of text.  It does allow Tektronix GIN mode, and in this mode
       the cursor will change from an arrow to a cross.  Pressing any key will
       send that key and the current coordinate of the cross cursor.  Pressing
       button one, two, or three will return the letters ``l'', ``m'', and
       ``r'', respectively.  If the ``shift'' key is pressed when a pointer
       button is pressed, the corresponding upper case letter is sent.  To
       distinguish a pointer button from a key, the high bit of the character
       is set (but this is bit is normally stripped unless the terminal mode
       is RAW; see tty(4) for details).

SELECT/PASTE
       X clients provide select and paste support by responding to requests
       conveyed by the server.

   PRIMARY
       When configured to use the primary selection, (the default) xterm can
       provide the selection data in ways which help to retain character
       encoding information as it is pasted.

       A user "selects" text on xterm, which highlights the selected text.  A
       subsequent "paste" to another client forwards a request to the client
       owning the selection.  If xterm owns the primary selection, it makes
       the data available in the form of one or more "selection targets".  If
       it does not own the primary selection, e.g., if it has released it or
       another client has asserted ownership, it relies on cut-buffers to pass
       the data.  But cut-buffers handle only ISO-8859-1 data (officially -
       some clients ignore the rules).

   CLIPBOARD
       When configured to use the clipboard (see resource selectToClipboard),
       the problem with persistence of ownership is bypassed.  Otherwise,
       there is no difference regarding the data which can be passed via
       selection.

   SELECTION TARGETS
       The different types of data which are passed depend on what the
       receiving client asks for.  These are termed selection targets.

       When asking for the selection data, xterm tries the following types in
       this order:
              UTF8_STRING
                   This is an XFree86 extension, which denotes that the data
                   is encoded in UTF-8.  When xterm is built with
                   wide-character support, it both accepts and provides this
                   type.

              TEXT the text is in the encoding which corresponds to your
                   current locale.

              COMPOUND_TEXT
                   this is a format for multiple character set data, such as
                   multi-lingual text.  It can store UTF-8 data as a special
                   case.

              STRING
                   This is Latin 1 (ISO-8859-1) data.

       The middle two (TEXT and COMPOUND_TEXT) are added if xterm is
       configured with the i18nSelections resource set to ``true''.

       UTF8_STRING is preferred (therefore first in the list) since xterm
       stores text as Unicode data when running in wide-character mode, and no
       translation is needed.  On the other hand, TEXT and COMPOUND_TEXT may
       require translation.  If the translation is incomplete, they will
       insert X's ``defaultString'' whose value cannot be set, and may simply
       be empty.  Xterm's defaultString resource specifies the string to use
       for incomplete translations of the UTF8_STRING.

       You can alter the types which xterm tries using the eightBitSelectTypes
       or utf8SelectTypes resources.  For instance, you might have some
       specific locale setting which does not use UTF-8 encoding.  The
       resource value is a comma-separated list of the selection targets,
       which consist of the names shown.  You can use the special name I18N to
       denote the optional inclusion of TEXT and COMPOUND_TEXT.  The names are
       matched ignoring case, and can be abbreviated.  The default list can be
       expressed in several ways, e.g.,

              UTF8_STRING,I18N,STRING
              utf8,i18n,string
              u,i,s

MENUS
       Xterm has four menus, named mainMenu, vtMenu, fontMenu, and tekMenu.
       Each menu pops up under the correct combinations of key and button
       presses.  Each menu is divided into sections, separated by a horizontal
       line.  Some menu entries correspond to modes that can be altered.  A
       check mark appears next to a mode that is currently active.  Selecting
       one of these modes toggles its state.  Other menu entries are commands;
       selecting one of these performs the indicated function.

       All of the menu entries correspond to X actions.  In the list below,
       the menu label is shown followed by the action's name in parenthesis.

   Main Options
       The xterm mainMenu pops up when the ``control'' key and pointer button
       one are pressed in a window.  This menu contains items that apply to
       both the VT102 and Tektronix windows.  There are several sections:

       Commands for managing X events:
              
              Toolbar
                     Clicking on the "Toolbar" menu entry hides the toolbar if
                     it is visible, and shows it if it is not.

              Secure Keyboard (securekbd)
                     The Secure Keyboard mode is helpful when typing in
                     passwords or other sensitive data in an unsecure
                     environment; see SECURITY below (but read the limitations
                     carefully).

              Allow SendEvents (allowsends)
                     Specifies whether or not synthetic key and button events
                     generated using the X protocol SendEvent request should
                     be interpreted or discarded.  This corresponds to the
                     allowSendEvents resource.

              Redraw Window (redraw)
                     Forces the X display to repaint; useful in some
                     environments.

       Commands for capturing output:
              
              Log to File (logging)
                     Captures text sent to the screen in a logfile, as in the
                     -l logging option.

              Print Window (print)
                     Sends the text of the current window to the program given
                     in the printerCommand resource.

              Redirect to Printer (print-redir)
                     This sets the printerControlMode to 0 or 2.  You can use
                     this to turn the printer on as if an application had sent
                     the appropriate control sequence.  It is also useful for
                     switching the printer off if an application turns it on
                     without resetting the print control mode.

       Modes for setting keyboard style:
              
              8-Bit Controls (8-bit-control)
                     Enabled for VT220 emulation, this controls whether xterm
                     will send 8-bit control sequences rather than using 7-bit
                     (ASCII) controls, e.g., sending a byte in the range
                     128-159 rather than the escape character followed by a
                     second byte.  Xterm always interprets both 8-bit and
                     7-bit control sequences (see the document Xterm Control
                     Sequences).  This corresponds to the eightBitControl
                     resource.

              Backarrow Key (BS/DEL) (backarrow key)
                     Modifies the behavior of the backarrow key, making it
                     transmit either a backspace (8) or delete (127)
                     character.  This corresponds to the backarrowKey
                     resource.

              Alt/NumLock Modifiers (num-lock)
                     Controls the treatment of Alt- and NumLock-key modifiers.
                     This corresponds to the numLock resource.

              Meta Sends Escape (meta-esc)
                     Controls whether Meta keys are converted into a
                     two-character sequence with the character itself preceded
                     by ESC.  This corresponds to the metaSendsEscape
                     resource.

              Delete is DEL (delete-is-del)
                     Controls whether the Delete key on the editing keypad
                     should send DEL (127) or the VT220-style Remove escape
                     sequence.  This corresponds to the deleteIsDEL resource.

              Old Function-Keys (oldFunctionKeys)
                     

              HP Function-Keys (hpFunctionKeys)
                     

              SCO Function-Keys (scoFunctionKeys)
                     

              Sun Function-Keys (sunFunctionKeys)
                     

              VT220 Keyboard (sunKeyboard)
                     These act as a radio-button, selecting one style for the
                     keyboard layout.  It corresponds to more than one
                     resource setting: sunKeyboard, sunFunctionKeys,
                     scoFunctionKeys and hpFunctionKeys ."

       Commands for process signalling:
              
              Send STOP Signal (suspend)
                     

              Send CONT Signal (continue)
                     

              Send INT Signal (interrupt)
                     

              Send HUP Signal (hangup)
                     

              Send TERM Signal (terminate)
                     

              Send KILL Signal (kill)
                     These send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM
                     and SIGKILL signals respectively, to the process group of
                     the process running under xterm (usually the shell).  The
                     SIGCONT function is especially useful if the user has
                     accidentally typed CTRL-Z, suspending the process.

              Quit (quit)
                     Stop processing X events except to support the -hold
                     option, and then send a SIGHUP signal to the the process
                     group of the process running under xterm (usually the
                     shell).

   VT Options
       The vtMenu sets various modes in the VT102 emulation, and is popped up
       when the ``control'' key and pointer button two are pressed in the
       VT102 window.

       VT102/VT220 Modes:
              
              Enable Scrollbar (scrollbar)
                     Enable (or disable) the scrollbar.  This corresponds to
                     the -sb option and the scrollBar resource.

              Enable Jump Scroll (jumpscroll)
                     Enable (or disable) jump scrolling.  This corresponds to
                     the -j option and the jumpScroll resource.

              Enable Reverse Video (reversevideo)
                     Enable (or disable) reverse-video.  This corresponds to
                     the -rv option and the reverseVideo resource.

              Enable Auto Wraparound (autowrap)
                     Enable (or disable) auto-wraparound.  This corresponds to
                     the -aw option and the autoWrap resource.

              Enable Reverse Wraparound (reversewrap)
                     Enable (or disable) reverse wraparound.  This corresponds
                     to the -rw option and the reverseWrap resource.

              Enable Auto Linefeed (autolinefeed)
                     Enable (or disable) auto-linefeed.  This is the VT102 NEL
                     function, which causes the emulator to emit a linefeed
                     after each carriage return.  There is no corresponding
                     command-line option or resource setting.

              Enable Application Cursor Keys (appcursor)
                     Enable (or disable) application cursor keys.  This
                     corresponds to the appcursorDefault resource.  There is
                     no corresponding command-line option.

              Enable Application Keypad (appkeypad)
                     Enable (or disable) application keypad keys.  This
                     corresponds to the appkeypadDefault resource.  There is
                     no corresponding command-line option.

              Scroll to Bottom on Key Press (scrollkey)
                     Enable (or disable) scrolling to the bottom of the
                     scrolling region on a keypress.  This corresponds to the
                     -sk option and the scrollKey resource.


                     As a special case, the XON / XOFF keys (control/S and
                     control/Q) are ignored.

              Scroll to Bottom on Tty Output (scrollttyoutput)
                     Enable (or disable) scrolling to the bottom of the
                     scrolling region on output to the terminal.  This
                     corresponds to the -si option and the scrollTtyOutput
                     resource.

              Allow 80/132 Column Switching (allow132)
                     Enable (or disable) switching between 80 and 132 columns.
                     This corresponds to the -132 option and the c132
                     resource.

              Keep Selection (keepSelection)
                     Tell xterm whether to disown the selection when it stops
                     highlighting it, e.g., when an application modifies the
                     display so that it no longer matches the text which has
                     been highlighted.  As long as xterm continues to own the
                     selection, it can provide the corresponding text to other
                     clients via cut/paste.  This corresponds to the
                     keepSelection resource.  There is no corresponding
                     command-line option.

              Select to Clipboard (selectToClipboard)
                     Tell xterm whether to use the PRIMARY or CLIPBOARD for
                     SELECT tokens in the translations resource which maps
                     keyboard and mouse actions to select/paste actions.  This
                     corresponds to the selectToClipboard resource.  There is
                     no corresponding command-line option.

              Enable Visual Bell (visualbell)
                     Enable (or disable) visible bell (i.e., flashing) instead
                     of an audible bell.  This corresponds to the -vb option
                     and the visualBell resource.

              Enable Bell Urgency (bellIsUrgent)
                     Enable (or disable) Urgency window manager hint when
                     Control-G is received.  This corresponds to the
                     bellIsUrgent resource.

              Enable Pop on Bell (poponbell)
                     Enable (or disable) raising of the window when Control-G
                     is received.  This corresponds to the -pop option and the
                     popOnBell resource.

              Enable Blinking Cursor (cursorblink)
                     Enable (or disable) the blinking-cursor feature.  This
                     corresponds to the -bc option and the cursorBlink
                     resource.  There is also an escape sequence (see the
                     document Xterm Control Sequences).  The menu entry and
                     the escape sequence states are XOR'd: if both are
                     enabled, the cursor will not blink, if only one is
                     enabled, the cursor will blink.

              Enable Alternate Screen Switching (titeInhibit)
                     Enable (or disable) switching between the normal and
                     alternate screens.  This corresponds to the titeInhibit
                     resource.  There is no corresponding command-line option.

              Enable Active Icon (activeicon)
                     Enable (or disable) the active-icon feature.  This
                     corresponds to the -ai option and the activeIcon
                     resource.

       VT102/VT220 Commands:
              
              Do Soft Reset (softreset)
                     Reset scroll regions.  This can be convenient when some
                     program has left the scroll regions set incorrectly
                     (often a problem when using VMS or TOPS-20).  This
                     corresponds to the VT220 DECSTR control sequence.

              Do Full Reset (hardreset)
                     The full reset entry will clear the screen, reset tabs to
                     every eight columns, and reset the terminal modes (such
                     as wrap and smooth scroll) to their initial states just
                     after xterm has finished processing the command line
                     options.  This corresponds to the VT102 RIS control
                     sequence, with a few obvious differences.  For example,
                     your session is not disconnected as a real VT102 would
                     do.

              Reset and Clear Saved Lines (clearsavedlines)
                     Perform a full reset, and also clear the saved lines.

       Commands for setting the current screen:
              
              Show Tek Window (tekshow)
                     When enabled, pops the Tektronix 4014 window up (makes it
                     visible).  When disabled, hides the Tektronix 4014
                     window.

              Switch to Tek Mode (tekmode)
                     When enabled, pops the Tektronix 4014 window up if it is
                     not already visible, and switches the input stream to
                     that window.  When disabled, hides the Tektronix 4014
                     window and switches input back to the VTxxx window.

              Hide VT Window (vthide)
                     When enabled, hides the VTxxx window, shows the Tektronix
                     4014 window if it was not already visible and switches
                     the input stream to that window.  When disabled, shows
                     the VTxxx window, and switches the input stream to that
                     window.

              Show Alternate Screen (altscreen)
                     When enabled, shows the alternate screen.  When disabled,
                     shows the normal screen.  Note that the normal screen may
                     have saved lines; the alternate screen does not.

   VT Fonts
       The fontMenu pops up when when the ``control'' key and pointer button
       three are pressed in a window.  It sets the font used in the VT102
       window, or modifies the way the font is specified or displayed.  There
       are several sections.

       The first section allows you to select the font from a set of
       alternatives:
              Default (fontdefault)
                     Set the font to the default, i.e., that given by the
                     *VT100.font resource.

              Unreadable (font1)
                     Set the font to that given by the *VT100.font1 resource.

              Tiny (font2)
                     Set the font to that given by the *VT100.font2 resource.

              Small (font3)
                     Set the font to that given by the *VT100.font3 resource.

              Medium (font4)
                     Set the font to that given by the *VT100.font4 resource.

              Large (font5)
                     Set the font to that given by the *VT100.font5 resource.

              Huge (font6)
                     Set the font to that given by the *VT100.font6 resource.

              Escape Sequence
                     This allows you to set the font last specified by the Set
                     Font escape sequence (see the document Xterm Control
                     Sequences).

              Selection (fontsel)
                     This allows you to set the font specified the current
                     selection as a font name (if the PRIMARY selection is
                     owned).

       The second section allows you to modify the way it is displayed:
              Line-Drawing Characters (font-linedrawing)
                     When set, tells xterm to draw its own line-drawing
                     characters.  Otherwise it relies on the font containing
                     these.  Compare to the forceBoxChars resource.

              Packed Font (font-packed)
                     When set, tells xterm to use the minimum glyph-width from
                     a font when displaying characters.  Use the maximum width
                     (unchecked) to help display proportional fonts.  Compare
                     to the forcePackedFont resource.

              Doublesized Characters (font-doublesize)
                     When set, xterm may ask the font server to produce scaled
                     versions of the normal font, for VT102 double-size
                     characters.

       The third section allows you to modify the way it is specified:
              TrueType Fonts (render-font)
                     If the renderFont and corresponding resources were set,
                     this is a further control whether xterm will actually use
                     the Xft library calls to obtain a font.

              UTF-8 (utf8-mode)
                     This controls whether xterm uses UTF-8 encoding of
                     input/output.  It is useful for temporarily switching
                     xterm to display text from an application which does not
                     follow the locale settings.

       The fourth section allows you to enable or disable special operations
       which can be controlled by writing escape sequences to the terminal.
       These are disabled if the SendEvents feature is enabled:
              Allow Color Ops (allow-font-ops)
                     This corresponds to the allowColorOps resource.  Enable
                     or disable control sequences that set/query the colors.

              Allow Font Ops (allow-font-ops)
                     This corresponds to the allowFontOps resource.  Enable or
                     disable control sequences that set/query the font.

              Allow Tcap Ops (allow-tcap-ops)
                     Enable or disable control sequences that query the
                     terminal's notion of its function-key strings, as termcap
                     or terminfo capabilities.  This corresponds to the
                     allowTcapOps resource.

              Allow Title Ops (allow-title-ops)
                     Enable or disable control sequences that modify the
                     window title or icon name.  This corresponds to the
                     allowTitleOps resource.

              Allow Window Ops (allow-window-ops)
                     Enable or disable extended window control sequences (as
                     used in dtterm).  This corresponds to the allowWindowOps
                     resource.

   TEK Options
       The tekMenu sets various modes in the Tektronix emulation, and is
       popped up when the ``control'' key and pointer button two are pressed
       in the Tektronix window.  The current font size is checked in the modes
       section of the menu.
              Large Characters (tektextlarge)
                     

              #2 Size Characters (tektext2)
                     

              #3 Size Characters (tektext3)
                     

              Small Characters (tektextsmall)
                     

       Commands:
              PAGE (tekpage)
                     Clear the Tektronix window.

              RESET (tekreset)
                     

              COPY (tekcopy)
                     

       Windows:
              Show VT Window (vtshow)
                     

              Switch to VT Mode (vtmode)
                     

              Hide Tek Window (tekhide)
                     

SECURITY
       X environments differ in their security consciousness.  Most servers,
       run under xdm, are capable of using a ``magic cookie'' authorization
       scheme that can provide a reasonable level of security for many people.
       If your server is only using a host-based mechanism to control access
       to the server (see xhost(1)), then if you enable access for a host and
       other users are also permitted to run clients on that same host, it is
       possible that someone can run an application which uses the basic
       services of the X protocol to snoop on your activities, potentially
       capturing a transcript of everything you type at the keyboard.  Any
       process which has access to your X display can manipulate it in ways
       that you might not anticipate, even redirecting your keyboard to itself
       and sending events to your application's windows.  This is true even
       with the ``magic cookie'' authorization scheme.  While the
       allowSendEvents provides some protection against rogue applications
       tampering with your programs, guarding against a snooper is harder.

       The possibility of an application spying on your keystrokes is of
       particular concern when you want to type in a password or other
       sensitive data.  The best solution to this problem is to use a better
       authorization mechanism than is provided by X.  Given all of these
       caveats, a simple mechanism exists for protecting keyboard input in
       xterm.

       The xterm menu (see MENUS above) contains a Secure Keyboard entry
       which, when enabled, attempts to ensure that all keyboard input is
       directed only to xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a password (or other sensitive data),
       you can enable Secure Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.  This ensures that
       you know which window is accepting your keystrokes.  It cannot ensure
       that there are no processes which have access to your X display that
       might be observing the keystrokes as well.

       Only one X client at a time can grab the keyboard, so when you attempt
       to enable Secure Keyboard it may fail.  In this case, the bell will
       sound.  If the Secure Keyboard succeeds, the foreground and background
       colors will be exchanged (as if you selected the Reverse Video entry in
       the Modes menu); they will be exchanged again when you exit secure
       mode.  If the colors do not switch, then you should be very suspicious
       that you are being spoofed.  If the application you are running
       displays a prompt before asking for the password, it is safest to enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt gets displayed correctly (in the new colors), to minimize the
       probability of spoofing.  You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm
       window becomes iconified (or otherwise unmapped), or if you start up a
       reparenting window manager (that places a title bar or other decoration
       around the window) while in Secure Keyboard mode.  (This is a feature
       of the X protocol not easily overcome.)  When this happens, the
       foreground and background colors will be switched back and the bell
       will sound in warning.

CHARACTER CLASSES
       Clicking the left pointer button twice in rapid succession
       (double-clicking) causes all characters of the same class (e.g.,
       letters, white space, punctuation) to be selected as a ``word''.  Since
       different people have different preferences for what should be selected
       (for example, should filenames be selected as a whole or only the
       separate subnames), the default mapping can be overridden through the
       use of the charClass (class CharClass) resource.

       This resource is a series of comma-separated of range:value pairs.  The
       range is either a single number or low-high in the range of 0 to 65535,
       corresponding to the code for the character or characters to be set.
       The value is arbitrary, although the default table uses the character
       number of the first character occurring in the set.  When not in UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

           static int charClass[256] = {
           /* NUL  SOH  STX  ETX  EOT  ENQ  ACK  BEL */

               48,  48,  48,  48,  48,  48,  48,  48};

       For example, the string ``33:48,37:48,45-47:48,38:48'' indicates that
       the exclamation mark, percent sign, dash, period, slash, and ampersand
       characters should be treated the same way as characters and numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

ACTIONS
       It is possible to rebind keys (or sequences of keys) to arbitrary
       strings for input, by changing the translations resources for the vt100
       or tek4014 widgets.  Changing the translations resource for events
       other than key and button events is not expected, and will cause
       unpredictable behavior.  The following actions are provided for use
       within the vt100 or tek4014 translations resources:

       allow-color-ops(on/off/toggle)
               This action set or toggles the allowColorOps resource and is
               also invoked by the allow-color-ops entry in fontMenu.

       allow-font-ops(on/off/toggle)
               This action set or toggles the allowFontOps resource and is
               also invoked by the allow-font-ops entry in fontMenu.

       allow-send-events(on/off/toggle)
               This action set or toggles the allowSendEvents resource and is
               also invoked by the allowsends entry in mainMenu.

       allow-tcap-ops(on/off/toggle)
               This action set or toggles the allowTcapOps resource and is
               also invoked by the allow-tcap-ops entry in fontMenu.

       allow-title-ops(on/off/toggle)
               This action set or toggles the allowTitleOps resource and is
               also invoked by the allow-title-ops entry in fontMenu.

       allow-window-ops(on/off/toggle)
               This action set or toggles the allowWindowOps resource and is
               also invoked by the allow-window-ops entry in fontMenu.

       alt-sends-escape()
               This action toggles the state of the eightBitInput resource.

       bell([percent])
               This action rings the keyboard bell at the specified percentage
               above or below the base volume.

       clear-saved-lines()
               This action does hard-reset() (see below) and also clears the
               history of lines saved off the top of the screen.  It is also
               invoked from the clearsavedlines entry in vtMenu.  The effect
               is identical to a hardware reset (RIS) control sequence.

       copy-selection(destname [, ...])
               This action puts the currently selected text into all of the
               selections or cutbuffers specified by destname.  Unlike
               select-end, it does not send a mouse position or otherwise
               modify the internal selection state.

       create-menu(m/v/f/t)
               This action creates one of the menus used by xterm, if it has
               not been previously created.  The parameter values are the menu
               names: mainMenu, vtMenu, fontMenu, tekMenu, respectively.

       dabbrev-expand()
               Expands the word before cursor by searching in the preceding
               text on the screen and in the scrollback buffer for words
               starting with that abbreviation.  Repeating dabbrev-expand()
               several times in sequence searches for an alternative expansion
               by looking farther back.  Lack of more matches is signaled by a
               beep().  Attempts to expand an empty word (i.e., when cursor is
               preceded by a space) yield successively all previous words.
               Consecutive identical expansions are ignored.  The word here is
               defined as a sequence of non-whitespace characters.  This
               feature partially emulates the behavior of ``dynamic
               abbreviation'' expansion in Emacs (bound there to M-/).  Here
               is a resource setting for xterm which will do the same thing:

                   *VT100*translations:    #override \n\
                        Meta <KeyPress> /:dabbrev-expand()


       deiconify()
               Changes the window state back to normal, if it was iconified.

       delete-is-del()
               This action toggles the state of the deleteIsDEL resource.

       dired-button()
               Handles a button event (other than press and release) by
               echoing the event's position (i.e., character line and column)
               in the following format:

                       ^X ESC G <line+`` ''> <col+`` ''>

       iconify()
               Iconifies the window.

       hard-reset()
               This action resets the scrolling region, tabs, window size, and
               cursor keys and clears the screen.  It is also invoked from the
               hardreset entry in vtMenu.

       ignore()
               This action ignores the event but checks for special pointer
               position escape sequences.

       insert()
               This action inserts the character or string associated with the
               key that was pressed.

       insert-eight-bit()
               This action inserts an eight-bit (Meta) version of the
               character or string associated with the key that was pressed.
               This only applies to single-byte values.  The exact action
               depends on the value of the metaSendsEscape and the
               eightBitInput resources.  The metaSendsEscape resource is
               tested first.


               The term "eight-bit" is misleading: xterm checks if the key's
               value is less than 128.  If so, xterm adds 128 to the value,
               setting its eighth bit.  Otherwise xterm sends an ESC byte
               before the key.  In other applications' documentation, that is
               referred to as a "meta key".

       insert-selection(sourcename [, ...])
               This action inserts the string found in the selection or
               cutbuffer indicated by sourcename.  Sources are checked in the
               order given (case is significant) until one is found.
               Commonly-used selections include: PRIMARY, SECONDARY, and
               CLIPBOARD.  Cut buffers are typically named CUT_BUFFER0 through
               CUT_BUFFER7.

       insert-seven-bit()
               This action is a synonym for insert() The term "seven-bit" is
               misleading: it only implies that xterm does not try to add 128
               to the key's value as in insert-eight-bit().

       interpret(control-sequence)
               Interpret the given control sequence locally, i.e., without
               passing it to the host.  This works by inserting the control
               sequence at the front of the input buffer.  Use "\" to escape
               octal digits in the string.  Xt does not allow you to put a
               null character (i.e., "\000") in the string.

       keymap(name)
               This action dynamically defines a new translation table whose
               resource name is name with the suffix Keymap (case is
               significant).  The name None restores the original translation
               table.

       larger-vt-font()
               Set the font to the next larger one, based on the font
               dimensions.  See also set-vt-font().

       load-vt-fonts(name[,class])
               Load fontnames from the given subresource name and class.  That
               is, load the "*VT100.name.font", resource as "*VT100.font" etc.
               If no name is given, the original set of fontnames is restored.


               Unlike set-vt-font(), this does not affect the escape- and
               select-fonts, since those are not based on resource values.  It
               does affect the fonts loosely organized under the ``Default''
               menu entry, including font, boldFont, wideFont and
               wideBoldFont.

       maximize()
               Resizes the window to fill the screen.

       meta-sends-escape()
               This action toggles the state of the metaSendsEscape resource.

       popup-menu(menuname)
               This action displays the specified popup menu.  Valid names
               (case is significant) include:  mainMenu, vtMenu, fontMenu, and
               tekMenu.

       print(printer-flags)
               This action prints the window and is also invoked by the print
               entry in mainMenu.


               The action accepts optional parameters, which temporarily
               override resource settings.  The parameter values are matched
               ignoring case:
               noFormFeed
                    no form feed will be sent at the end of the last line
                    printed (i.e., printerFormFeed is ``false'').

               FormFeed
                    a form feed will be sent at the end of the last line
                    printed (i.e., printerFormFeed is ``true'').

               noNewLine
                    no newline will be sent at the end of the last line
                    printed, and wrapped lines will be combined into long
                    lines (i.e., printerNewLine is ``false'').

               NewLine
                    a newline will be sent at the end of the last line
                    printed, and each line will be limited (by adding a
                    newline) to the screen width (i.e., printerNewLine is
                    ``true'').

               noAttrs
                    the page is printed without attributes (i.e.,
                    printAttributes is ``0'').

               monoAttrs
                    the page is printed with monochrome (vt220) attributes
                    (i.e., printAttributes is ``1'').

               colorAttrs
                    the page is printed with ANSI color attributes (i.e.,
                    printAttributes is ``2'').

       print-everything(printer-flags)
               This action sends the entire text history, in addition to the
               text currently visible, to the program given in the
               printerCommand resource.  It allows the same optional
               parameters as the print action.  With a suitable printer
               command, the action can be used to load the text history in an
               editor.

       print-redir()
               This action toggles the printerControlMode between 0 and 2.
               The corresponding popup menu entry is useful for switching the
               printer off if you happen to change your mind after deciding to
               print random binary files on the terminal.

       quit()  This action sends a SIGHUP to the subprogram and exits.  It is
               also invoked by the quit entry in mainMenu.

       readline-button()
               Supports the optional readline feature by echoing repeated
               cursor forward or backward control sequences on button release
               event, to request that the host application update its notion
               of the cursor's position to match the button event.

       redraw()
               This action redraws the window and is also invoked by the
               redraw entry in mainMenu.

       restore()
               Restores the window to the size before it was last maximized.

       scroll-back(count [,units [,mouse] ])
               This action scrolls the text window backward so that text that
               had previously scrolled off the top of the screen is now
               visible.


               The count argument indicates the number of units (which may be
               page, halfpage, pixel, or line) by which to scroll.


               An adjustment can be specified for these values by appending a
               "+" or "-" sign followed by a number, e.g., page-2 to specify 2
               lines less than a page.


               If the third parameter mouse is given, the action is ignored
               when mouse reporting is enabled.

       scroll-forw(count [,units [,mouse] ])
               This action is similar to scroll-back except that it scrolls in
               the other direction.

               used with select-cursor-start.

       select-cursor-extend()
               This action is similar to select-extend except that it should
               be used with select-cursor-start.

       select-cursor-start()
               This action is similar to select-start except that it begins
               the selection at the current text cursor position.

       select-end(destname [, ...])
               This action puts the currently selected text into all of the
               selections or cutbuffers specified by destname.  It also sends
               a mouse position and updates the internal selection state to
               reflect the end of the selection process.

       select-extend()
               This action tracks the pointer and extends the selection.  It
               should only be bound to Motion events.

       select-set()
               This action stores text that corresponds to the current
               selection, without affecting the selection mode.

       select-start()
               This action begins text selection at the current pointer
               location.  See the section on POINTER USAGE for information on

               This action sets the font or fonts currently being used in the
               VT102 window.  The first argument is a single character that
               specifies the font to be used:
               d or D indicate the default font (the font initially used when
                        xterm was started),
                       

               1 through 6 indicate the fonts specified by the font1 through
                        font6 resources,
                       

               e or E indicate the normal and bold fonts that have been set
                        through escape codes (or specified as the second and
                        third action arguments, respectively), and
                       

               s or S indicate the font selection (as made by programs such as
                        xfontsel(1)) indicated by the second action argument.
                       


              If xterm is configured to support wide characters, an additional
              two optional parameters are recognized for the e argument: wide
              font and wide bold font.

       smaller-vt-font()
               Set the font to the next smaller one, based on the font

               have a modern version of the process filesystem, e.g., "/proc",
               which xterm can read.


               Use the "cwd" process entry, e.g., /proc/12345/cwd to obtain
               the working directory of the process which is running in the
               current xterm.


               On systems which have the "exe" process entry, e.g.,
               /proc/12345/exe, use this to obtain the actual executable.
               Otherwise, use the $PATH variable to find xterm.


               If parameters are given in the action, pass them to the new
               xterm process.

       start-extend()
               This action is similar to select-start except that the
               selection is extended to the current pointer location.

       start-cursor-extend()
               This action is similar to select-extend except that the
               selection is extended to the current text cursor position.

       string(string)
               This action inserts the specified text string as if it had been
               typed.  Quotation is necessary if the string contains
               whitespace or non-alphanumeric characters.  If the string
               argument begins with the characters ``0x'', it is interpreted
               as a hex character constant.

       tek-copy()
               This action copies the escape codes used to generate the
               current window contents to a file in the current directory
               beginning with the name COPY.  It is also invoked from the
               tekcopy entry in tekMenu.

       tek-page()
               This action clears the Tektronix window and is also invoked by
               the tekpage entry in tekMenu.

       tek-reset()
               This action resets the Tektronix window and is also invoked by
               the tekreset entry in tekMenu.

       vi-button()
               Handles a button event (other than press and release) by
               echoing a control sequence computed from the event's line
               number in the screen relative to the current line:

                       ESC ^P
               or
                       ESC ^N

               according to whether the event is before, or after the current
               line, respectively.  The ^N (or ^P) is repeated once for each
               line that the event differs from the current line.  The control
               sequence is omitted altogether if the button event is on the
               current line.

       visual-bell()
               This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
               This action sends the indicated graphics input code.

       The default bindings in the VT102 window use the SELECT token, which is
       set by the selectToClipboard resource:

       The default bindings for the scrollbar widget are separate from the
       VT100 widget:

                                 <Btn5Down>: StartScroll(Forward) \n\
                                 <Btn1Down>: StartScroll(Forward) \n\
                                 <Btn2Down>: StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
                                 <Btn3Down>: StartScroll(Backward) \n\
                                 <Btn4Down>: StartScroll(Backward) \n\
                                 <Btn2Motion>: MoveThumb() NotifyThumb() \n\
                                 <BtnUp>:    NotifyScroll(Proportional) EndScroll()


       The default bindings in the Tektronix window are:

                            ~Meta<KeyPress>: insert-seven-bit() \n\
                             Meta<KeyPress>: insert-eight-bit() \n\
                           !Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
                      !Lock Ctrl <Btn1Down>: popup-menu(mainMenu) \n\
            !Lock Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
                 !Ctrl @Num_Lock <Btn1Down>: popup-menu(mainMenu) \n\
                           !Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
                      !Lock Ctrl <Btn2Down>: popup-menu(tekMenu) \n\
            !Lock Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
                 !Ctrl @Num_Lock <Btn2Down>: popup-menu(tekMenu) \n\
                      Shift ~Meta<Btn1Down>: gin-press(L) \n\
                            ~Meta<Btn1Down>: gin-press(l) \n\
                      Shift ~Meta<Btn2Down>: gin-press(M) \n\
                            ~Meta<Btn2Down>: gin-press(m) \n\
                      Shift ~Meta<Btn3Down>: gin-press(R) \n\
                            ~Meta<Btn3Down>: gin-press(r)


       Here is an example which uses shifted select/paste to copy to the
       clipboard, and unshifted select/paste for the primary selection.  In
       each case, a (different) cut buffer is also a target or source of the
       select/paste operation.  It is important to remember however, that cut
       buffers store data in ISO-8859-1 encoding, while selections can store
       data in a variety of formats and encodings.  While xterm owns the
       selection, it highlights it.  When it loses the selection, it removes
       the corresponding highlight.  But you can still paste from the
       corresponding cut buffer.

           *VT100*translations:    #override \n\
               ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
               Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
               ~Shift<BtnUp>:       select-end(PRIMARY, CUT_BUFFER0) \n\
               Shift<BtnUp>:        select-end(CLIPBOARD, CUT_BUFFER1)


       Below is a sample how of the keymap() action is used to add special
       keys for entering commonly-typed works:

           *VT100.Translations: #override <Key>F13: keymap(dbx)
           *VT100.dbxKeymap.translations: \
                <Key>F14: keymap(None) \n\
                <Key>F17: string("next") string(0x0d) \n\
                <Key>F18: string("step") string(0x0d) \n\
                <Key>F19: string("continue") string(0x0d) \n\
                <Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)


       Some people prefer using the left pointer button for dragging the
       scrollbar thumb.  That can be setup by altering the translations
       resource, e.g.,

           *VT100.scrollbar.translations:     #override \n\
                <Btn5Down>:    StartScroll(Forward) \n\
                <Btn1Down>:    StartScroll(Continuous) MoveThumb() NotifyThumb() \n\
                <Btn4Down>:    StartScroll(Backward) \n\
                <Btn1Motion>:  MoveThumb() NotifyThumb() \n\
                <BtnUp>:  NotifyScroll(Proportional) EndScroll()


CONTROL SEQUENCES AND KEYBOARD
       The Xterm Control Sequences document lists the control sequences which
       an application can send xterm to make it perform various operations.
       Most of these operations are standardized, from either the DEC or
       Tektronix terminals, or from more widely used standards such as
       ISO-6429.

ENVIRONMENT
       Xterm sets several environment variables:

       DISPLAY
            is the display name, pointing to the X server (see DISPLAY NAMES
            in X(7)).

       TERM is set according to the termcap (or terminfo) entry which it is
            using as a reference.

       WINDOWID
            is set to the X window id number of the xterm window.

       XTERM_LOCALE
            shows the locale which was used by xterm on startup.  Some shell
            initialization scripts may set a different locale.

       XTERM_SHELL
            is set to the pathname of the program which is invoked.  Usually
            that is a shell program, e.g., /bin/sh.  Since it is not
            necessarily a shell program however, it is distinct from
            ``SHELL''.

       XTERM_VERSION
            is set to the string displayed by the -version option.  That is
            normally an identifier for the X Window libraries used to build
            xterm, followed by xterm's patch number in parenthesis.  The patch
            number is also part of the response to a Secondary Device
            Attributes (DA) control sequence (see Xterm Control Sequences).

       Depending on your system configuration, xterm may also set the
       following:

       COLUMNS
            the width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to update utmp.

       LINES
            the height of the xterm in characters (cf: "stty rows").

       LOGNAME
            when xterm is configured to update utmp.

       SHELL
            when xterm is configured to update utmp.  It is also set if you
            provide the shell name as the optional parameter.

       TERMCAP
            the contents of the termcap entry corresponding to $TERM, with
            lines and columns values substituted for the actual size window
            you have created.

       TERMINFO
            may be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on your system.

       /etc/utmp
            the system logfile, which records user logins.

       /etc/wtmp
            the system logfile, which records user logins and logouts.

       /etc/X11/app-defaults/XTerm
            the xterm default application resources.

       /etc/X11/app-defaults/XTerm-color
            the xterm color application resources.  If your display supports
            color, use this
                      *customization: -color
            in your .Xdefaults file to automatically use this resource file
            rather than /etc/X11/app-defaults/XTerm. If you do not do this,
            xterm uses its compiled-in default resource settings for colors.

ERROR MESSAGES
       Most of the fatal error messages from xterm use the following format:
              xterm: Error XXX, errno YYY: ZZZ
       The XXX codes (which are used by xterm as its exit-code) are listed
       below, with a brief explanation.

       1    is used for miscellaneous errors, usually accompanied by a
            specific message,

BUGS
       Large pastes do not work on some systems.  This is not a bug in xterm;
       it is a bug in the pseudo terminal driver of those systems.  xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but some pty drivers do not return enough information to know if the
       write has succeeded.

       Many of the options are not resettable after xterm starts.

       This program still needs to be rewritten.  It should be split into very
       modular sections, with the various emulators being completely separate
       widgets that do not know about each other.  Ideally, you'd like to be
       able to pick and choose emulator widgets and stick them into a single
       control widget.

       There needs to be a dialog box to allow entry of the Tek COPY file

OPENBSD SPECIFICS
       On OpenBSD, the following resources have different default values:

       allowFontOps: false
               

       allowWindowOps: false
               Various, potentially dangerous, extended window control
               sequences are disabled.

       deleteIsDEL: true
               The Delete key generates ^?.

       ptyInitialErase: true
               The erase character for the tty is inherited from the parent
               process setting, generally ^?.

       backarrowKeyIsErase: true
               The back arrow key is set to return the erase character defined
               in the tty, generally ^?.

       Moreover, on OpenBSD the termcap(5) entry for xterm defines the kb
       capability as ^?
