Hello. Since an update (I think it's an update…), I no longer have the use of the left/right keys on the keyboard (useful for doing frame by frame on the timeline, for example ). Couldn't find the solution, it's not the keyboard (tested another one) and it's the program (because the keys work on Word, in Mail, etc.) I'm on Mac Os. Did I disable the keys? How ? Can we recover their use? Thank you for your reply.
