hkey15.txt is revision 1.5 of Quake Handy Keys. This is a much improved
version of the document. It is now in a much more "FAQ" style format. Also,
much more info. Be sure to check out Aftershock: A Quake Webzine at the
following address: http://www.nuqneH.org/aftershock/index.html.
This page has many links and lots of info, plus soon it will have an 
HTMLized version of the handy keys. Share and Enjoy!
