At the bottom of every Nexus 7 screen, no matter what you're do-
ing, you'll always find these three navigation buttons:
Opens the previous screen you were working in, even
if it was in a different app. Once you back up to the
Home screen, you can't go back any further in your
Opens Home. If you're viewing a left or right Home
screen, opens the central Home screen. To open
Google Now, swipe up. Google Now gives just what
you need to know, right when you need it.
Opens a list of thumbnail images of apps you've
worked with recently. To open an app, touch it. To re-
move a thumbnail from the list, swipe it left or right.
If you don't use these buttons often, they may shrink to dots or
fade away, depending on the current app. To bring them back,
touch their location.
