There are a number of neat features bundled into your Mac that make it super useful and fun!

Assign Dashboard and Exposé actions to the corners of your desktop and trigger them with a swipe of the mouse.

From now on, you'll have to be more careful when you move your mouse, but you'll quickly get the hang of it. You'll have instant access to features that will greatly improve your workflow with quick mouse movements.

This is particularly useful when you need to drag an object to a desktop covered in windows. (Assign the Desktop action to a corner, and drag your object to that corner to clear it.)
