I have been exploring the OS X accessibility option to control the mouse from your keyboard (as described here) and I am curious if there is a way to make it go faster.
KeyRemap4Mac is a nice program that has a large number of various configurations which allow you to modify the function of your keyboard, including the ability to speed up you mouse navigation via the keyboard!

Step 1: First I turn off Mouse Keys, then I open Terminal and execute this command:
defaults write com.apple.universalaccess "mouseDriverInitialDelay" 0.05
After re-enabling, mouse starts moving almost immediately.
Step 2: Install the demo version of ControllerMate ( http://controllermate.com ), and create something similar:
Now pressing the Ctrl key will act as a turbo key, moving your mouse very fast instantly. (If anybody knows an alternative to the otherwise great ControllerMate, please leave a comment.)
