Apple has introduced iPad gesture control since last year in iOS 4.3 as a developer option and in October with the debut of iOS 5, these multi-finger gestures goes official. There’s no more pressing the button to return to home screen and hardware button for switching back and forth between apps. These may makes the navigation workflow even faster and no more extra efforts in tapping button. Below are the few summary of the multi-gestures which available for iPad navigation besides standard two-finger pinching and double-tap to zoom functions. In order for you to use this, you can go do so by turn it on at Settings > General > Multitasking Gestures > On / Off.
Five-finger pinch: You just “grab” the screen at any point to get back to Home screen, well its much faster with this trick.
Four-finger swipe up: This gestures will bring up the multitasking bar and recently used apps. Here you can pick a different app and by swipe four fingers back down will hide the multitasking bar.
Four-finger swipe left / right: If you do not use much on the multitasking bar, you can make this gesture to quickly moves you through running and most recently used apps. You can quickly swipe between opened apps such as Mail, Safari and even Kindle apps one after another.
Lastly, you can remove apps from your multitasking bar with your four-fingers gesture swipe up to show currently running and used apps. Then tap on any of these apps to get into editing mode and tap on the upper corner left badge with the red minus sign and remove any app you wish. After you done with that, you can bring back down the bar by simple four-fingers swipe down.
