Add an extra pedal to your car...
Foot pedal control...
This footswitch is basically an office joke. Click the button and it minimizes all the screens on your desktop. Well, I got my hands on one by accident and a managed a nifty little addition to the car.
When you plug it in, don't install the software, just let xp identify it as a Human Interface Device. Open up girder and hit it and it actually registers a single code. Now, by itself one button doesn't do much. But tack on this modified GML file which performs different actions based on the number of clicks per second, and you have a nifty way to control your music/video/whatever.
Mine is setup to control winamp and is placed on the far left from the brake pedal. One click=Pause....Two Clicks=Next Track....Three Clicks=Previous Track. I don't think you can really go above that and have it be effective, but the GML file can hold up to 9 actions.
Just reset the Events in the Action directory to do what you want and redirect the actions in the cyclic event folder to target your new events. Viola! Makes it very easy to skip through music while never even taking your hands off the wheel!
P.S. - You'll need to enable the keyboard and alarm timer plugins for this to work properly
