New glyphs, old kerning

Having finished and kerned a master, I needed to make an additional k.alt glyph. It should take its right side kerning values from the x.alt glyph. The x.alt isn’t in a kerning group, but the two glyphs should form a new kerning group together.

Is there an easy way to do this?

Add a class for both glyphs, open the Kerning panel, click the button in the lower right and select “Compress”. The makes class kerning from all glyph kerning if they have a class and the class has no kerning value. Please check your exceptions as they might be converted to class kerning if there was no class kerning for that pair.

An other way is tho filter for the x.alt and click all pairs and close the lock on each pair.

Thanks Georg, that did the trick. Luckily I didn’t have any pre-exsisting exceptions.
