AltGr is used to write characters that might not otherwise be
accessible on the keyboard -- you hold AltGr down and press another
key.  Here some examples that work on my keyboard:

      AltGr e = €
      AltGr r = ®
      AltGr c = ©
      AltGr d = ð

But exactly what you get by using AltGr (if anything) probably depends
on you locale settings.

On many (European) keyboards the right Alt key is labeled as AltGr.

If you never need AltGr I suppose it's easiest just to map the right
Alt key to Alt rather than AltGr.
