Robot Remote Control Page Needs Help!

Hi all-

I need help with a robotics remote control page.


Currently you use the site at the bottom to control the robot by clicking the arrows (and each arrow is a submit button of a form).

I want to be able to do this with the arrow keys of my keyboard. Site only needs to work in firefox. Either help me with what I’m doing wrong, or give me a new solution.

~Thanks in Advanced
