OK, so I'm going to put this question out here again, because I never did get an answer. So using Ableton on a Mac, is anyone or has anyone experienced the issue where option right arrow just doesn't work? This is a showstopper for me.
@Brynify Something that happens to me is that I can't use cmd left/right to navigate between clips on a track or inside the clip/midi editor. i have to use cmd option left/right arrow instead. Maybe something like that will work for you as well? What are you trying to do?
