It would be nice to be able to hit - and + to zoom in and out of the animation timeline.
+1 - Actually, as we all develop our own workflows, it'd sure be nice if we could create our own custom "map keys". I'm getting into a lot more demand for animations thanks to the powerful results from KeyShot. However, during set-ups, I'd sure like to be able to navigate the model tree much quicker, in particular "collapsing all" in the tree. I know I can right click in the tree and drag down to "collapse all", but a command key like 'c' or 'ca', BOOM, I'm already there. ;)
