Non-Keyboard Push To Talk Button

[Dathus]

I know the post title sounds really stupid but it isn't. I play a game, Final Fantasy XI, and I need to move around and hit macros as I talk sometimes. On Ventrillo I was able to make it so my USB attached PS2 controller could be used as a PTT key, and I was wondering if there is a way to make that happen again? It makes things so much easier, as I don't have to lean down to my laptop and hit a button while talking to my group while we do something, just lean back and hold L1 down as I use the control sticks to run around and continue doing other things.

TS can not do that directly.

If you can make the L1 a keyboard key and then make that the TS PTT button then it will work.
