I remember, in Dope Sheet, using Shift while dragging keyframes (I always use G) to be more precise. With 2.7, that doesn't work. I tried with 2.66... and it neither! Tried 2.57... and neither.
Am I wrong and this function never existed... or there was a version that supported it?
EDIT: I don't want to move to decimal frames (eg: 24.534). As commented, I want to move keyframes in a zoomed-out-view and be precise when dropping them.
