Instead of gruff messages like
Buffer is read-only: #<buffer *Ibuffer*>
Buffer is read-only: #<buffer *List Options*>
when one hits an unbound key,
or flashing of the terminal (BBDB mode),
helpful messages like
Commands: m, u, t, RET, g, k, S, D, Q; q to quit; h for help, or
new field: C-o; edit field: e; delete field: d; mode help: C-h m; info: i
could be put in the minibuffer.

That would suck.

BTW, an unbound key signals a "KEY is undefined" error.  I think you
are talking about keys bound to self-insert-command.

I dunno, maybe showing a huge help message immediately would suck, but
the general idea of having a buffer/region-specific alternative error
message for trying to modify read-only text would be a good thing --
I think there are many cases where the current error _is_ confusing,
especially to those without much Emacs experience.

I'd rather be consing.

You can have a region-somewhat-specific error message by using a
string-valued `read-only' text property (in Emacs 22):

    (insert (propertize "xxx" 'read-only "Bork Bork Bork!"))

    An attempt to modify the text displays

        Text is read-only: "Bork Bork Bork!"


This feature seems to be undocumented.

I will document that.  Thanks for pointing out the deficiency.
