> C-c C-f runs the command gnus-summary-mail-forward (found in
> gnus-summary-mode-map), which is an autoloaded interactive
> native-compiled Lisp function in ‘gnus-msg.el’.
> 
> It is bound to C-c C-f and S o m.
> 
> (gnus-summary-mail-forward &optional ARG POST)
> 
> Forward the current message(s) to another user.
> If process marks exist, forward all marked messages;
> if ARG is nil, see ‘message-forward-as-mime’ and ‘message-forward-show-mml’;
> if ARG is 1, decode the message and forward directly inline;
> if ARG is 2, forward message as an rfc822 MIME section;
> if ARG is 3, decode message and forward as an rfc822 MIME section;
> if ARG is 4, forward message directly inline;
> otherwise, use flipped ‘message-forward-as-mime’.
> If POST, post instead of mail.
> For the "inline" alternatives, also see the variable
> ‘message-forward-ignored-headers’.
