question about StarOffice completion

["Robert P. Goldman" <goldman@htc.honeywell.com>]

Has anyone out there figured out how to accept a completion that the
StarOffice text editor proposes?  It's driving me crazy right now ---
StarOffice quite often guesses which word I want to be typing, but I
can't figure out how to say "ok, you're right."  Every key press I
come up with just wipes out the proposed new word.  

I'd RTFM but, of course, there is no M!  I tried buying a book about
StarOffice, and looking at the "help" files (I think that's "help" as
in "we need help" not as in "we give help").

Thanks!
Robert
