OS X the most advanced operating system on the market today introduced Gestures with the release of OS X 1.07 (Lion) and the Magic Trackpad. By default OS X only gives you a standard set of Gestures that can't be modified and you can't add any custom defined Gestures. To fill this gap developer Andreas Hegenberg from Munich released the third-party application, BetterTouchTool.
This application allows you to configure many gestures for your Magic Mouse, Macbook Trackpad and Magic Trackpad. It also allows you to configure actions for keyboard shortcuts, normal mice and the Apple Remote. In addition to this it has an iOS companion App, which can also be configured to control your Mac the way you want. You can use many different Gestures to interact with your OS X system some of our favorites are:
• Three Finger Tap (Tap with three fingers)
• Three Finger Swipe Up (move three fingers up at the same time)
• Three Finger Swipe Down (move three fingers down at the same time)
• Four Finger Click (click with four fingers on the mouse)
• Four Finger Swipe Up (move four of your fingers up at the same time)
• Four Finger Swipe Down (move four of your fingers down at the same time)
Groups of gestures can be assigned to specific applications, or made global. The latest version includes presets (which you can switch between), import, and export. Separate gestures are available for the trackpad and the Magic Mouse, and the new "Live View" feature makes it very easy to gain precise control over sensitivity settings and to test out gestures.
BetterTouchTool is a free download, requires Mac OS X 10.6 (Snow Leopard) and either the Magic Mouse or multitouch capable MacBook or MacBook Pro to use.
