New trackpad gestures

Apple introduced two-finger and three-finger multitouch gestures back when the first MacBook Air was released, but Snow Leopard adds four-finger gestures, previously available only on recent models, to a bunch of older laptops. Swipe four fingers down the trackpad to enter and exit Exposé’s Application mode; swipe four fingers up the trackpad to access Exposé’s Desktop mode. By swiping all four fingers left or right, you bring up OS X’s application switcher (normally accessed by pressing Command-Tab); click on a program’s icon to switch to it.
