Apple® iPad® - Slide Over
The Slide Over feature allows you to work with a second app without leaving the one you're in.
This feature is only available on the iPad Air 2 and later devices.
While using an app, slide your finger from the bottom up to reveal the dock.
From the list that appears, tap and hold the app you would like to access.
If you have used Slide Over previously from the open app, your other app is presented (you don't have to select from a list).
Slide your finger up and release the selected app on the screen.
