Where's my keys at?

[Alexy Khrabrov <braver@xxxxxxxxx>]

I compiled an S-Lang version of mutt-1.5.4j and suddenly
PgUp/PgDn keys don't work in index.  Saying 
bind generic <pagedown> next-page
doesn't change that, mutt says Key is not bound.
Apparently, it thinks the key sends something else.
Is there an emacs-like way, C-h k, to see what the
key is sending?  Is it s-lang-specific and can be 
controlled through s-lang library settings?
