## Style

## Add

Click this button to add the symbol shown in the right preview window to the current symbol set. It will be saved under the name displayed in the Symbol list box. You must specify a name under Symbol or Symbol Set to be able to use this button. Names cannot be used more than once.

### Moving a Symbol to Another Symbol Set

As an example, to transfer the large ALPHA from the "Greek" set to the "Special" set, select the old set (Greek) and then the ALPHA symbol using the two top list boxes. The symbol appears in the left preview window. In the \<emph\>Symbol set\</emph\> list box, select the "Special" set. Click \<emph\>Modify\</emph\> and then \<emph\>OK\</emph\>. The ALPHA symbol is now only in the "Special" symbol set.

## Delete

Click to remove the symbol shown in the left preview window from the current symbol set. There will be no security query. Deleting the last remaining symbol of a symbol set also deletes the symbol set.

You can also click \<emph\>Cancel\</emph\> at any time to close the dialog without saving any of the changes.
