The shortcuts I use most are for zooming. I have a terrible time zooming any other way. Ctrl+F is quite useful as well!
 
Another Side-Note, I found that I need to perform a Ctrl+Shift+A before I export anything to ensure I'll REALLY get the "Entire Mix". It's habit-forming. I despise short-cuts, but when I have to use them, I get somewhat comfortable.
 
It'll probably be another few years before I see a dire need for touch, but Skylight needs some tweaking for touch to be as useful as I'd want to see. Slate's figured that one out, albeit with a limited vision. I've suggested to CW a better way of doing this than Slate. I dunno if it fell through the cracks or not, though.
