You can add one or more composite glyph members to an empty glyph, which will turn the empty glyph into a composite glyph. You can also add more glyph members to existing composite glyphs. If you wish to edit an empty glyph or modify a composite glyph you can select Glyph from the Insert menu.

 

In the Select Composite Glyph Member window, select the glyph(s) you want to add to the composite glyph and press the OK button.
