Here's what I picked up from a website about a month ago (and my left
pinkey is much happier now):

;; Automatically indent the next line...
(mapcar
 (lambda (mode)
   (let ((mode-hook (intern (concat (symbol-name mode) "-hook")))
         (mode-map  (intern (concat (symbol-name mode) "-map"))))
     (add-hook mode-hook
               `(lambda nil
                  (local-set-key (kbd "RET")
                                 (or (lookup-key ,mode-map "\C-j")
                                     (lookup-key global-map "\C-
j")))))))
