just to be clear. the problem was not that i couldn’t figure out the zoom zap function. the problem was that the manual is incomplete. and it is not only the zoom zap thats missing. i had previous problems with searching help and pdf for a menu specific item and not being able to find it. i did not pursue it on those occasions so i can’t be more specific.
thanks to youtube tutorials filling the gap!
otherwise cubase 12 is working very well so far!
