Mouse Gestures - Firefox Add-ons
Mouse gestures provide computer users with a third way to carry out commands, after the keyboard and the menu system. They can benefit users with certain kinds of visual or movement impairments, and they also provide a way for power users to speed up their work -- and impress their friends! Here are some of the mouse gesture program options for Ubuntu.
Firefox add-ons -- FireGestures and EasyGestures
The simplest option is to obtain a simple add-on for Firefox, the default web browser. There are several of these, obtainable from https://addons.mozilla.org (search for 'gestures'), covering a range of options. The most popular is currently FireGestures, which allows the user to carry out familiar tasks like opening new tabs and windows, jumping to hyperlinks and retracing their steps back through their browsing history via combinations of mouse gestures. These are done while holding down the right mouse button, and there is an option to turn on a green 'trail' which allows the user to see the shape of the gesture as they do it -- handy for novices.

FireGestures uses simple combinations of linear movements -- up and down, left and right -- plus combinations of the Ctrl, Shift and Alt keys. A different approach is taken by EasyGestures, another Firefox add-on which pops up a donut-shaped icon menu around the mouse cursor when the middle button is pressed. The options on the menu are customisable and can include opening and closing windows, browsing through tabs, and all the options available through the standard menu system. Both programs support 'rocker' movements -- holding down one mouse button while pressing another.
