Exposé is a great way to streamline your interaction with Mac OS X, but how can your interaction with exposé be streamlined? First, open System Preferences, and then select the Exposé & Spaces pane. Now, go to the Exposé tab. In the area labeled Active Screen Corners, you can set specific Exposé functions like displaying your desktop or displaying the dashboard.
Now whenever your mouse hits an active hot corner, your computer will perform that Exposé action. This is a great time saver, but it sure will confuse the heck out of your friends when they use your computer.
