Editing Class-Based Kerning
To define kerning for a class you need to define the kerning for the key
glyph of the class using the standard tools of the Metrics panel in kerning
mode.
When you enter glyphs that are used as key glyphs into the kerning-editing
string and select a pair of them for kerning editing you will see two buttons
appear below the glyph images:
If you click on one of these buttons you will see a popup menu that lists all
classes where the glyph works as a key glyph:
Select the class name and it opens for preview in the Classes panel.
Similar buttons appear when you edit kerning using the Kerning Editor
dialog box:
Their purpose is the same – to preview classes in which the currently
selected glyph serves as a key glyph.
