In Flash CS6 when animating frame-by-frame by hand, I'm constantly toggling onion skinning on and off, and the same with the "loop" button right next to it for looping a certain range of frames. Neither of these appears to be assignable to a hotkey, meaning I need to take the mouse/pen away from the drawing and hit these buttons several times a minute, really putting a damper on the workflow.
Might we be able to get this in the next patch? It seems like a no-brainer, especially for a program that many people use for hand-drawn animation projects.
Bumping thread from the dead, as it's baffling that this has yet to be addressed.
Onion Skin, Loop Within Range, etc, can now be set in the keyboard shortcuts window. A very recent addition is that once you have set a key, the key you have used also shows in the help tip.
I'm not sure what key makes sense though! As I'm on Mac I used ctrl-O and ctrl-L. Not that I have to toggle them too often.
Sweet, that's great that this is now a thing, even if it's just going forward. I have yet to play around in Animate CC as of yet, but it's nice to see progress like this.
