The Alt + Tab key allows you to quickly switch between applications in Windows. With Android, you can access just a single application at any one time, but it has its own version of the Alt + Tab shortcut to switch between applications.

Tap and hold the Home key in the notification area of the Android screen and a window will pop up showing you a list of running application. The apps that you have running will be listed in this window and to open one of them just click on the name/icon.

This is a nice handy shortcut. Don’t forget to share it!
