Navigation gestures for Magic Mouse
You can swipe between pages and full-screen apps, as well as activate Mission Control, using gestures on the Magic Mouse. Navigating pages can be done with one or two fingers. If you set it to one, make sure you uncheck the ’Swipe between full-screen apps option’ in the More Gestures tab of the Mouse pane to avoid confusion. If you don’t use Mission Control, uncheck the box that allows you to activate it with double-tap. Finally, to check your mouse’s battery level, click on the Bluetooth menu bar item and hover over the Mouse that's connected.
