[snip useful code]

Basically, a much more efficient version of what I eventually came up
with:

guint unshift_keysym(guint keysym)
{
  /* Oh boy is this ugly! */
  return XKeycodeToKeysym(gdk_display,
                          XKeysymToKeycode(gdk_display,keysym),
                          0);
}

Slow and ugly, but it works :-)

Thanks for the help!

Cheers,

Phil
