Hi,
A number of speedbar's bindings, such as 'n' and 'p', do not work with
view-mode enabled in the speedbar buffer (which makes no sense anyway).
This is relevant when view-read-only is set, causing speedbar-mode to
implicitly enable view-mode.
For my part, I have redefined speedbar-mode in my .emacs file as follows:
(require 'speedbar)
(defvar real-speedbar-mode #'speedbar-mode)
(defun speedbar-mode ()
(let ((view-read-only nil))
(funcall #'real-speedbar-mode)))
This appears to solve the problem. speedbar-mode calls
toggle-read-only; binding view-read-only to nil around that call should
be a more permanent fix.
M-x emacs-version
GNU Emacs 23.2.1 (x86_64-pc-linux-gnu, GTK+ Version 2.20.1) of
2010-09-26 on falconsrevenge
Thanks,
Ryan Twitchell

Why does it do this, as opposed to `(setq buffer-read-only t)'?
(I notice a few other files call toggle-read-only as well. Seems odd.)

A fair question. I suppose this is just caution: toggle-read-only will
always "do the right thing" to make sure the buffer is read-only, though
setting buffer-read-only should be sufficient.

That doesn't make sense to me. I replace several inappropriate uses,
including the speedbar one.
I wonder if toggle-read-only should even be added to
byte-compile-interactive-only-functions.

I wonder as well. I know I'm to blame for some of the calls to
toggle-read-only, because I thought it might be better to use the
higher-level function. But indeed it seems that was a mistake.
So let's add it to byte-compile-interactive-only-functions (with
a comment about why); and if it turns out that there are many cases
where calling it from Elisp makes sense, then we'll get to learn which
are the cases where it makes sense.
