C-u runs universal-prefix-arg. What you want to do is to get the
description of the function run by the key "f", and read that to see
how the behavior is modified by a prefix arg. For example to see what
happens with C-u M-; ...
C-h k M-;
,----
| M-; runs the command comment-dwim
| which is an interactive compiled Lisp function in `newcomment'.
| (comment-dwim ARG)
|
| Call the comment command you want (Do What I Mean).
| If the region is active and `transient-mark-mode' is on, call
| `comment-region' (unless it only consists of comments, in which
| case it calls `uncomment-region').
| Else, if the current line is empty, insert a comment and indent it.
| Else if a prefix ARG is specified, call `comment-kill'.
| Else, call `comment-indent'.
`----
This tells me that M-; runs comment-dwim (do what i mean). The second
line up from the bottom says that with a prefix arg (meaning that I
hit C-u first), it will run comment-kill instead.
