Editor: 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?
Rocker is portable, so you can grab just the .exe here. It's also open source, so you can check out the source code here. Rocker is written in Autohotkey.
Changelog:
Version 0.2: Added a fix for right-click drag bug, added more program support, tweaked Explorer navigation.
Version 0.1: Released
Bug reports and feature requests: The first release of Rocker only includes gestures for a few programs (Windows Explorer, Firefox, Internet Explorer, iTunes, and Notepad++), so I'm hoping to gather requests from readers so that I can build up a more robust list of built-in gestures.
