Oh, not quite.  Right now, there's for example a "[C]ompose a new mail"
text where the C also has a keymap property which would invoke the
respective command on mouse-2 and RET.  `substitute-command-keys'
doesn't allow doing that out of the box.  So one would need to iterate
over occurrences of the help-key-binding face afterwards, translate back
to the command and add a keymap property.

How do I lookup a command for the printed key description?

  (keymap-lookup nil "C-c C-c")
  ;=> message-send-and-exit

works but is too new to be used for packages supporting older emacsen.
Is

  (lookup-key (current-local-map) (kbd "C-c C-c"))

the right incarnation?
