OS X Tip: Open all windows from the dock

I've slowly come to love OS X Expose. It's moved me away from browser tabs and towards using F9 to view all windows in miniature.

Problem is, docked Windows don't show up, and there's no obvious way to undock them all.

The answer -- hold down the Option (alt) key and click on any docked window -- all windows for that app will undock.

I discovered this one simply by assuming someone at Apple would have a fix, and knowing that the Option key is often used for this sort of thing.
