(click the 'options' tab, or press 'R' to open the info box while you're working)
This version has hotkeys for every button in the program, thanks to DD, and I added a nice built-in list for quick reference while you're animating.

The list was added to the options form because it's the only pop-up that you can keep open while you're still animating (others like the 'about' box must be closed before you can go back to pivot, so you can't have them both open at once.)
