Make your own glyphs set and save yourself the trouble of repeatedly hunting and pecking around in the Glyphs palette to find the special characters you’re after. This is especially useful if you need to mix and match glyphs from different fonts. Two minor gripes: there’s no way to make your own custom glyph, nor is it possible to share a glyph set among a workgroup.
The Glyphs palette, available under the Type menu, allows access to the font’s full character set, as well as allowing you to view subsets: Ornaments, Oldstyle figures, Discretionary Ligatures, and so on. Creating your own glyph set saves you the trouble of hunting and pecking for the special characters you need.
