X Window, Right Ctrl -> Control?

[joost witteveen]

Hello all,

Could anyone tell me how to make the right Ctrl key work
(just as the left one) as Control? At the moment it seems
to do just nothing (although xev does notice it).

I've tried adding 
  RightCtl    Control
to my /etc/X11/XF86Control file, but that doesn't seem to work.
(I'm using XFree 3.1.6 now, but will switch to 4.0 if that's what
it takes).

Thanks!
