I notice now in H21 when I move keyframe it was done freely on both time or value, without any "lock" .
Before (in H20.5) when starting to move key horizontally, we only move in time and any futher vertical movement do nothing. that's really usefull. Same for value when we start to move verticaly.
Now in H21 moving keyframes was not locked in any direction (time or value)
cf. video record for a better explain
Question : does I miss a new shortcut or option to move key only in time OR only in value ?
