When working with video timeline I am painting and panning the canvas with the space bar key. But when I press spacebar and not pan it starts to play the timeline and the play head moves to the next layer which is very annoying. This problem was reported a long time ago but the problem is not fixed yet. There whould be a way to disable the shortcut key for the play button in the video timeline. Else the video time line is a feature of no use for animation artists trying to create animations in Photoshop. Just cant work with this. Please fix the problem. Its been really long since this bug got fixed.
