Contextually select all glyphs NOT in a given class

[carlelkins]

Hi everyone,

Is there any way to invoke all glyphs (in this case I’m contextually kerning) that are NOT in a given class, without creating a separate class containing said glyphs?

I’ve tried a preliminary search here on the forums, but I couldn’t find anything (and I have a feeling it isn’t possible, or I probably would have come across it in the tutorials).

Thanks for any help!

Carl

This is what the ‘ignore’ keyword is for. About the details check the Adobe FDK feature file spec.

That works perfectly! And thank you both for the links. They’ve already been very helpful!
