Mission Control >
Though it’s smaller than the Magic Trackpad, the Magic Mouse isn’t incapable. For example, double-tapping two fingers on its surface opens Mission Control.
Swipe full-screen apps >
If you’ve set up multiple desktops or are running several apps in full-screen mode, switch between them by swiping two fingers left or right on your Magic Mouse.
Smart zoom>
Need to take a closer look at a document or web page? Turn on ‘Smart zoom’ in the Mouse preferences pane, then double-tap the mouse’s surface to zoom in or out.
Swipe between pages>
Whether you’re browsing the web using Safari, a simple swipe with one finger left or right across the Magic Mouse will take you to the next or previous page.
