Metrics Assistance
Another way to use a kerning class is to adjust the metrics (advance width
and left and right sidebearings) in the glyphs that belong to the class. Use
the Tools > Metrics assistance command to open the Metrics assistance
dialog box:
It has a toolbar, a list of the kerning classes, a command area, a preview
panel and a class information panel that lets you change class definitions
and define new classes.
Before you start working with the class metrics, define some classes. You
can do that inside the Metrics assistance dialog box, but adding classes
with the Class panel is much easier.
