Multitouch or Multitasking gestures are one of the coolest features of iOS for the iPad. With these gestures, you can easily and quickly switch between apps, return back to the main screen (home screen), close apps, and much more.
How to enable Multitasking Gestures
First make sure that you have enabled Multitasking Gestures. To turn this on, simply tap Settings > General > Multitasking Gestures and toggle this ON.
Now you can use either four or five fingers to perform various multitouch tasks as follows:
Close Apps and Pinch to the Home Screen
You can use four or five fingers in a pinching gesture to get back to the home screen, instead of pressing the home button. It is quick and simple.
Open Multitasking bar
You want to open your multitasking bar to force close an app or switch between apps? You may do so by clicking the home button twice. You can also do this with multitasking gestures by using four or five finger to swipe up.
Switch apps by swiping left or right
This is one of the most useful of the multitasking gestures. You can switch between apps by using four or five fingers and swiping left or right.
