Foot Pedals - for when you are out of fingers

footswitch I tried to make an app to help vision impaired people navigate the screen by using eye tracking. The goal was to not have to lift the hands from the keyboard. But I eventually gave up because it can be much easier done with a foot pedal.

I ordered a FS3-P USB 3 Triple Foot Switch Pedal form eBay. When connected to a computer acts as a normal USB Keyboard but with just three keys.

I used the software USB-Overdrive to run scripts when one of the pedals is pressed.

    end tell
