Sorry if it is too much noob question, but I could not find info on it.
So I was wondering is it possible? I am working with a timelines now for boss animations and there are a lot of times when I need to change length of some movement in middle of timeline , but keeping time length of all remaining keyframes. Selecting by mouse takes a lot of time when you have minute+ length with 100+ frames. I feel there must be a keyboard shortcut for this. Is there? Also there is high chance that r401 will crash during selection of multiple keyframes by mouse.
