Switching applications in Exposé

Apple published a new “Tip of the Week”, describing how to switch from app to app in Exposé. I can’t believe I’ve never done this before, this will sure come in handy.

Apple describes how to do this:
Once you have Exposé invoked (you pressed either F9 or F10), you can toggle through your open applications and Finder windows by pressing the Tab key. Press the Tab key once and the next open application and its miniaturized windows come to the front. Press Tab again, it goes to the next open app. Want the previous app? Press Shift-Tab.
