Actually, it was probably written by someone who DOESN'T know what he/she is
talking about. Johann de Koening (sp?) is the programmer of The King, which is
the guts of CM6K. I doubt he has anything to do with the UI, and especially the
documentation, as English is not his first language. So you should probably
trust your own instincts before trusting the text.
