    Eli> Yes.

You could do something like this to economise on typing:

(defun display-help-string ()
    (when-let* ((help (help-at-pt-kbd-string)))
      (message "%s" (substitute-command-keys help))))
(add-hook 'post-command-hook #'display-help-string nil t)

(hmm, would it make sense to add something like that to eldoc?)
