Rocker is a mouse navigation tool that lets you perform common tasks, like moving forward and backward in your browser, by simply rocking your fingers across your left and right mouse buttons.
Rock what now? Basically, a mouse rocker gesture requires that you press one mouse button, hold it down, then press the other. You can rock across the mouse from right-to-left or left-to-right; each direction you rock gives you a different result. Once you get used to this gesture, the name makes perfect sense, and you'll wonder why you weren't mouse rocking your whole life.
