How to Use Multi-touch Gestures on the iPad
In addition to the tried-and-true pinch-to-zoom, iOS 5 includes a few new gestures to make iPad navigation faster and easier.
One-finger flick: Scroll through apps, different modes in the camera, and through web pages.
Four or five-finger flick: Swipe up to reveal all of your open apps as well as Control Center.
Four-finger swipe: Move left or right to switch between open apps.
Pinch-to-close: Pinch the screen with five fingers to close an app and return to the home screen.
Pinch-to-zoom: In apps like Maps, pinch out with two fingers to zoom in.
