Screen Corners

Here's a cool trick that utilizes some hidden features of your operating system and increases your productivity. It's called Screen Corners and it allows you to put "hot corners" on your Desktop so when you move your mouse to a certain position it performs an action. Some examples of things you can do are put your computer to sleep, show all of your applications, start your screen saver, show your desktop or your Dashboard.

To enable Screen Corners go to the Apple (top left corner) and choose System Preferences and then Expose and Spaces. Click on the Expose tab and then play around with the settings until you get what you want. Now try it out and see what you can do.
