This is probably a really stupid question, but what does the F7 key on the MBP do when I don't hold the fn key (like the F1/F2 control brightness, etc.) It shows what look like cascading windows, but it doesn't seem to do that.

I think it switches between mirroring and spanning for multiple displays.

I thought that might be it, but I haven't had a chance to try it. I'll see if I can find a 2nd display to try it sometime today.

It does what Chuckit said.
