Let me be a little more clear about what I am trying to accomplish.

I understand how to create a keymap and how to use define-minor-mode
to create a mode that makes use of my keymap.

What I wanted to do was to assign my keymap to the \C-b key in the
LaTeX-mode-map in AucTeX.  Is there a way of doing that in my minor
mode package or do I need to add something to my .emacs to accomplish
this?

This is what I have so far but I haven't found a way of getting
what I am looking for yet.

------------------------------------------------------------------------

(defvar bibs-map nil "\
Keymap containing bindings to the Bibs functions.")

(define-prefix-command 'bibs-map)           ;;; <---Is this necessary?

(define-key bs-map "g" 'bibs-get-ref)
(define-key bs-map "v" 'bibs-find-v-num)
(define-key bs-map "f" 'bibs-fix-quotes)

(define-minor-mode bibs-mode
   ""
   ;; Initial Value
   nil
   ;; The indicator for the mode line
   " Bibs"
   ;; The minor mode bindings
   'bs-map
   (...)           ;;; <------ Is there something I can put here
                   ;;; to associate the (unused) \C-b key in AucTeX
                   ;;; LaTeX-mode-map as a prefix key for bibs-map?
   )


------------------------------------------------------------------------

Alternatively, I could (if necessary) put something in my .emacs that
associates bibs-map with the \C-b in LaTeX-mode-map.  I just don't know
how to do that.

Also, when I toggle off bibs-mode it should remove the keymap from the
\C-b prefix key in LaTeX-mode-map, right?  Again, how do I do that?
