Jim Hamm starts out with, "I was 'messing' (technical term) around with Snow Leopard and came across a feature that might be helpful. Say you've got four windows open (or any number, for that matter) and you click Function 9 (fn+9) on your laptop, to open all windows in a miniature version. Put your cursor on any minimized window, then tap the spacebar. That window will pop open to full size. Then start moving your mouse and cursor around. Each small window will pop open in full size. Keep moving your mouse around and around and each window will pop open. When you find the one you want, click it. It will stabilize then in a normal window. You can almost make yourself dizzy as you mouse the cursor around the screen and the windows pop open."
He says on Zee's iMac the key combination in fn + F8.
Trying to do this myself turns up a different scenario. Different Macs have different Function keys. On his G4 PowerBook running Mac 10.5.8 Don's favorite is F12 to bring up his Widgets. On my MacBookPro running Snow Leopard, it's F4 for Widgets, and F3 for that nifty feature Jim describes to play Hide and Peek with your open pages. Yes, it's fun!
Now for a summary of Function Keys, a list of key combinations, and 20+ links to additional info on modifier keys assignments go to this Apple Support page. No need to memorize the whole thing, just click on the tiny Plus sign on the left of the page's address at the top. Click to add it to your Safari Bookmarks. Function keys are very useful.
