Someone in the newsgroup has a keyboard where typing '#' is difficult
or impossible to do, and mentioned that he could use Alt+r to get #rub but
was playing a knight and had no way to get #ride. Turns out that there
are several normal-mode extended commands that lacked a meta shortcut.
Since meta chars are case sensitive, I've added Alt+R for #ride, plus
M-A for #annotate, M-O for #overview, M-C for #conduct, and M-T for #tip.
Unfortunately, I've been unable to test them. It turns out that
nethack mode in PuTTY doesn't change the Alt key into a meta shift, it
causes the digits on the number pad to send vi-style movement letters
(with support for shift+digit and ctrl+digit to send modified letters).
That seems relatively useless to me, and I haven't figured out how to
force on high bit for arbitrary characters so can't activate nethack's
meta-key shortcuts.
The Guidebook has been updated via copy+paste and is untested too.
