No, abnt2 has an additional numpad key.  Most keyboards have only one,
which is KPDOT.  In US kbd layout this actually maps to a dot.  On other
layouts (german for example) it maps to comma.  Probably because
different countries use different chars as decimal separator.  abnt2 is
unique here, it has both comma and dot.

cheers,
