Entering coordinates on a USB keypad.

[Glen1980]

I have bought a Canon LS-120PC calculator/keypad to go on the left of my keypad so I can work without taking my hand from the trackball when entering figures into tables, drawing to coord etc.

 

So far it has worked fine but I still have to use the comma button for coordinates, is there either an alternative to using the comma for coordinates or a way of reprogramming the keyboard through windows. I am still on XP and only have LT so LISP won't help but put it up anyway it might help someone else plus IT are supposed to be installing the office copy to my machine.
