trouble overwriting C-r in a shell (term-mode)

[Christian Seberino]

I'm trying to overwrite C-r in a shell and it isn't working.
Any help greatly appreciated.  I tried adding a term-mode hook as
follows....

(add-hook 'term-mode-hook
          '(lambda () (interactive)
                   (global-set-key (kbd "C-r")
                                   (lambda () (interactive)
                                              (if (get-buffer  "*Open
Recent*")
                                                  (kill-buffer "*Open
Recent*"))
                                              (recentf-open-files)))))

Thanks!

Chris
