Seamless Multi-Touch Surface
Magic Mouse is an advanced point-and-click mouse that lets you click and double-click anywhere on its Multi-Touch surface.
Magic Mouse functions as a two-button mouse when you enable Secondary Click in System Preferences. Left-handed users can reassign left and right click, as well.
Brush one finger along the Multi-Touch surface to scroll in any direction and to pan a full 360 degrees.
Hold down the Control key on your keyboard and scroll with one finger on Magic Mouse to enlarge items on your screen.
Using two fingers, swipe left and right along the Multi-Touch surface to advance through pages in Safari or browse photos in iPhoto.
