Rocker 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.

What it does: Rocker adds mouse rocker navigation to many popular windows programs, allowing you to, for example, navigate forward and backward in your favorite web browser by rocking your fingers across the mouse keys.

Usage: I first became familiar with mouse rocker gestures while using Opera, which comes with them built in. Eventually I found a Firefox extension that incorporated mouse rocking, but I soon found myself wanting it in every application I frequently worked in - namely Windows Explorer, iTunes, and Notepad++.

In Firefox, for example, rocking your mouse buttons from left-to-right will move forward, while right-to-left will move back a page. The same basic thing is true of Explorer. In iTunes, left-to-right tracks forward, while right-to-left tracks back. In Notepad++, left-to-right rocking switches tabs to the right, right-to-left switches tabs to the right. Make sense?
