I'm in the middle of compiling a handy cheat-sheet of all the assorted keyboard shortcuts, and what they'll do. I'll share when I'm done, but I could use some help assembling a complete list.
So far, this is what I have:
Note, I write control here, but it'll be ctrl/cmd in the final document for iPuters ;)
