Thank you! Because these methods could be used by other processors, I've
used your pictures and some text to update the page at:

http://www.piclist.com/techref/io/keyswitch.htm

Please let me know if I've missed anything...

Ok, let my try to get a better reaction:

EVERY single way that YOU can think of to decode a keypad is ALREADY listed
at 
http://www.piclist.com/techref/io/keyswitch.htm and NOBODY can think of
another way to do it!

There, that ought to get some new ideas posted.
