hi Janet,
you place one finger at the bottom of the screen and slide it up.
you will feel tiny vibrations and hear a pip style tone.
if you release on the second pip tone it will take you to the home screen, and
if you release on the third pip tone it will take you into your open apps list.
you can do similar but sliding down from the top in which case the second pip
tone takes you into the control centre and the third pip tone will take you
into notifications.
pete.
