Scripting Fkey for +/- mouse acceleration

[apoch]

OSX.3.7

I am trying to figure out how to script/command a couple of Fkeys to reduce/speed up mouse acceleration.

There used to be a com.apple.mouse.scaling.plist but I see it is missing now. Creating this file does nothing.

Having this function would be fantastic for quickly reducing Mouse tracking speed for detailed graphics.

Thank you for any ideas or pointers to how to manually change mouse tracking speed via Key Commands.

cheers!
