CTRL-Select multiple Second Kern Pair Groups in OpenType Designer

Yes, I saw your post that you added not long ago.

Manually kerning thousands or tens of thousands of pairs is a waste of time — that’s probably why no one does it unless they don’t know how to use autokern and kerning classes. After running Autokern on my fonts, I manually check half a dozen pairs that I know are likely to be wrong, like C hyphen. If I am being very picky, I manually skim through several hundred pairs of kerning classes. I might do this for the first (Regular) style of a font, but I then import the *.otlfd script into the other styles, and just run Autokern again to update the pairs for the new style, then manually check just the known troublesome pairs.
