It was, C-c C-o involves 3 key presses.  F7 involves one.

This is what I get in *Messages*:

with (define-key ess-mode-map [f7] 'ess-comint-kill-output)
eval: Symbol's value as variable is void: ess-mode-map

with (global-set-key [f7] 'comint-kill-output)

So, does that mean I have to define 'comint-kill-output

Thanks for the help.
