   No, that's the best way to do it.  But you can just use Joe
   Cornell's caps-mode.el minor mode, posted to gnu.emacs.sources
   last month (and consider using the suggestions posted by me and
   Kim Storm in followup messages).

Thanks for the suggestions and the ping Kevin.  BTW, its "CORNELI"
:). Here is a revised version of the mode, incorporating everyone's
nice suggestions and one additional fix, and giving credit to all.

Tested GNU Emacs 21.3.1 (i386-pc-linux-gnu, X toolkit) of 2003-10-31
on raven, modified by Debian

;;; caps-mode.el -- (minor mode) letters are inserted capitalized

;;; Commentary:          

;; This is a simple minor mode in which all letters are inserted in
;; captialized form.  I haven't bothered with letters outside of

;; Note that this mode has absolutely nothing to do with the toggle
;; state of your capslock.

;;; Code:

(defun caps-mode-self-insert-command (&optional n)
  "Like `self-insert-command', but upcase the the typed character."
  (interactive "p")   
  (insert-char (upcase last-command-char) n))

(defvar caps-mode-map
  (let ((map (make-sparse-keymap)))
    (mapc (lambda (char)
               (char-to-string char)

(define-minor-mode caps-mode
  "Toggle caps mode.
With no argument, this command toggles the mode.
Non-null prefix argument turns on the mode.
Null prefix argument turns off the mode.

When caps mode is enabled, all letters are inserted in their
capitalized form."
  :init-value nil
  :lighter " Caps")
;;; caps-mode.el ends here
