Hello,
I have a following keybinding, parts of which do not work.  In
particular I am trying to bind view-previous-entry to the page-up key
on the standard PC keyboard (using Emacs 22.1).  I used both h-k and h-
l to determine that this key is identified with "<prior>" & <next>".
(defvar iop-alert-mode-map nil
  "Keymap for IOP-alert mode")
(unless iop-alert-mode-map
  (setq iop-alert-mode-map (copy-keymap text-mode-map))
  (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)
  (define-key iop-alert-mode-map (kbd "<next>") 'view-next-entry)
  (define-key iop-alert-mode-map (kbd "d") 'mark-entry-for-deletion)
  (define-key iop-alert-mode-map "m" 'mark-entry-for-save))
When in a buffer with iop-alert mode, doing h-m gives me the following
output on keybindings:
... stuff skipped
< n e           Prefix Command
< p r           Prefix Command
< n e x         Prefix Command
< p r i         Prefix Command
< n e x t       Prefix Command
< p r i o       Prefix Command
< n e x t >  view-next-entry
< p r i o r     Prefix Command
< p r i o r >        view-previous-entry
It seems <prior> and <next> are bound to the character sequence
"<prior>" and "<next>".  Pressing those characters will invoke the
commands.  But pressing the Page-up/down keys will not.
Indeed, doing a h-k shows that page-up/down are still bound to scroll
up/down.
What am I doing wrong?
emacs-version   --> "22.2.1"
(kbd "<prior>") --> [prior]
if you don't get this vector with one symbol for (kbd "<prior>"),
indeed you have a problem.

I tried that, and I get exactly as you suggested.
(kbd "<prior>") --> [prior]

It looks like you have been doing

  (define-key iop-alert-mode-map "<prior>" 'view-previous-entry)

instead of

  (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)

Nope.  This is what I have

 (define-key iop-alert-mode-map (kbd "<prior>") 'view-previous-entry)

Pascal is right: _something_ has bound "<prior>" in iop-alert mode.
Perhaps there is another library earlier in load-path, or an out-of-date
compiled version of the library.
