I love the new Magic Mouse however I really missed the center click and squeeze. There is a way to closely mimic those actions under the “Expose & Spaces” preference panel. Set an action by holding down any combination of shift+control+option and/or command with “Second mouse click” and you’ll regain similar functionality that the “Mighty Mouse” had.
Apple unveils the new multi-touch wireless Magic Mouse.
The new mouse does more than let you right- and left-click. You can use a single finger to scroll around—not just up and down or side to side, either. Within supported apps, such as Preview, you can scroll in any direction.
The Magic Mouse also supports swipe gestures, though not the same ones you’ll find in Apple’s multi-touch trackpads. Swiping left with two fingers in Safari will move you back a page, and in a stack of images in iPhoto, swiping left or right with two fingers will take you to the previous or next photo, respectively.
