Oh yeah, I forgot to mention how to change it. It's in the default controls file but not in the menu, so just remove that line or change it manually by editing the controls file. It should be in the same place as your VDrift.config, something like C:\Documents & Settings\protomor\.vdrift\controls.
Since it doesn't have a file extension Windows will not recognize this file as a text file. You'll probably have to use Open With to open it. Also the crappy text editors that come with windows don't support Unix style text files, so you'll need something better (like
Notepad++ or
Notepad2) to edit them properly.
