The latest Macbooks have a great multi-touch trackpad. Even when I am using an external keyboard and mouse, I often reach for the trackpad.
I knew it was capable of handling multiple gestures. I didn’t know how capable though until I stumbled into the Trackpad System Preferences application. They have video demonstrations inside the app.
You can view the demonstration and setup your Trackpad by clicking the System Preferences and choosing the Trackpad configuration application.
