In time, the correlation between physical motion and virtual reaction becomes second nature, and allows for very quick computing.
Multitouch gestures allow you to input a physical motion on the trackpad in place of a keyboard or virtual menu command on your computer. For anyone who does not use gestures already, they're extremely helpful. I decided to forage and hack my way through the 'about:config' tangles of Firefox on the rumor that a 'gesture' filter would uncover the precious Firefox 4 update that included multitouch gestures. I searched on the internet, but really found only moderate amounts of help, aimed at computer geniuses. As a long time user of the Multiclutch, which lets anyone configure their own multitouch gesture commands, I was concerned when my custom gestures stopped working for the new 64 bit Firefox 4.
