i use an onscreen keyboard because i cant type so i cant play without it, anyways i have a problem, when i push f11 to see the demographics screen it minimises the keyboard and i have to quit to bring it back up so i need help finding the file which controls this so i can modify it, im new to this stuff.

I don't think it's possible. As far as I know, there's no way of changing the hotkeys in the game.
