Hi Hafiz,
From the Tools menu, select Options and go to the General tab and uncheck
the boxes against "Help for WordPerfect users" and "Navigation keys for
WordPerfect users"
Please post any further questions or followup to the newsgroups for the
benefit of others who may be interested. Unsolicited questions forwarded
directly to me will only be answered on a paid consulting basis.
Hope this helps
