So there's nothing wrong with my syntax, just something else
incompatible?  Is one method preferable to the other?

Defining f7 as (global-set-key [f7] 'comint-kill-output) and pressing
the F7 key while in the *R* buffer, the Message buffer lists:

Symbol's function definition is void: comint-kill-output

That same message appears at the bottom of the Emacs window.

Defining f7 as (define-key ess-mode-map [f7] 'ess-comint-kill-output)
and pressing the F7 key while in the *R* buffer, the Message buffer
lists nothing though "<f7> is undefined" appears at the bottom of the
window.


I didn't follow how to use C-x C-e in the *scratch* buffer so I can't
provide that output.  My bad.

Thanks for the feedback.
