Unity editor 'PLAY' button using gamepad button?

Is there a way to 'press the play button' (the one that starts your game in the editor) by pressing the physical 'play' button on my gamepad?

Ideally, it would be a global hotkey, so I could press it while in the code editor, and it would focus the Unity window and start the game.

I think it may be impossible, at least without some extra non-unity tool, but I thought I'd just ask
