Re: Accessibility of Gnome panel / How to end session via keyboard

["Padraig O'Briain" <Padraig Obriain Sun COM>]

I have answered the questions I can. I  think that you need to ask the other on 
a gnome mailing list. See http://mail.gnome.org/mailman/listinfo. Perhaps 
gnome-list or desktop-devel

I just use the patch command.

Try http://www.cvshome.org
