Greetings! Please move this thread if it is not in the correct place.

Basically, I would like to add some custom action to the keybinding Fn+F8 on my Thinkpad T61. Right now, with SHMConfig enabled using the Preferences menu, it's action is to toggle enable/disable the touchpad. I'm trying to find out where this action is actually taking place. Is this a script command tied to the binding? I've used xev, gconf, etc. to try and find out the action for this key and haven't seen any.

If anyone knows how this is being implemented, please let me know. Thank you so much in advanced!
