Couldn't find a thread on this.
I'll start with StrokesPlus:
Heavily customisable mouse gestures for Windows. I've tried a few of them, and this is the only one that offers the depth I need through a simple scripting language.
The basic idea is that you hold down the right mouse(or other if you prefer) button and draw a symbol to perform a task. Some of the ones I use most regularly (these are all modified with a right click):
-Volume up/down with scroll wheel
-Draw up to open new Chrome tab from anywhere
-Draw down to minimise any window
-Paste with left click
-Control music/movies being played
-All tab functionality in browser
I'd recommend at least trying these out for your browser (there are extensions for Chrome/Firefox at least).
If anyone wants help with scripts, I'll do my best to help.
