I did this and it works well enough. I now have an auto updated rdictcc
buffer when scrolling around in w3m or article buffers. Thanks for your
help. Maybe some sort of timer would be nice so it only updates the
rdictcc buffer after resting on the same word for a while - but that is
a little beyond my current experience at the moment. Another nice
addition might be to be able to set the rdictcc window height so its
always a fixed height at the bottom of the frame.

You can toggle the rdictcc auto update using f5-o in the code below.

(setq show-translations nil)

(defun mytranslate()
  (interactive)
;  (save-window-excursion
  (message "myt")
  (save-selected-window
    (let ((word (rdictcc-current-word)))
      (when (and word show-translations)
        (rdictcc-translate-word word)
        )
      )
    )
  )

(add-hook 'w3m-after-cursor-move-hook 'mytranslate)

(global-set-key (kbd "<f5> T") 'mytranslate)
(global-set-key (kbd "<f5> o") (lambda()(interactive)(setq show-translations 
(not show-translations))))

(define-key gnus-article-mode-map [right] (lambda () 
(interactive)(mytranslate)(forward-char)))
(define-key gnus-article-mode-map [left] (lambda () 
(interactive)(mytranslate)(backward-char)))
(define-key gnus-article-mode-map [up] (lambda () 
(interactive)(mytranslate)(previous-line)))
(define-key gnus-article-mode-map [down] (lambda () 
(interactive)(mytranslate)(next-line)))
