You want to look at column editing mode (part of cua mode) see

I'm not sure if you mean this but you can use M-; command to comment a
region. Major modes should define the comment style for the language.
For example, message-mode uses "> " as comment characters. If you want
to change the default then I think this will do:

    (set (make-local-variable 'comment-start) "> ")
    (set (make-local-variable 'comment-start-skip) ">+[ \t]*")

quoting a block of text with ">"

[Stever]

I can't seem to find this function in my version of emacs, but I assume
there is one. is there any function where I can highlight a block of text
and put a ">" in front of it. So something like:

The quick brown fox jumps over the lazy dog. The quick brown fox jumps
over the lazy dog. The quick brown fox jumps over the lazy dog. The quick
brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy
dog. The quick brown fox jumps over the lazy dog.

It's part of mail-indent-citation (in sendmail.el):

    (save-excursion
      (let ((end (set-marker (make-marker) (region-end))))
        (goto-char (region-beginning))
        (while (< (point) end)
          (insert mail-yank-prefix)
          (forward-line 1))))

mail-yank-prefix is "> " in this case.

This assumes you have the block of text marked as region.

While not obvious, `string-rectangle' is your friend here:

  string-rectangle is an interactive autoloaded Lisp function in
  `rect.el'.
  
  It is bound to C-x r t.
  
  (string-rectangle START END STRING)
  
  Replace rectangle contents with STRING on each line.
  The length of STRING need not be the same as the rectangle width.

Put cursor at the beginning of the first line of the region, set the
mark, move cursor to the _beginning_  of the last line, then
press

C-x r t > <ENTER>

(there is a space entered after ">").

Or, for that matter, easily

* put an arbitrary number of ">" in front, i.e. quote to a level. 
* remove an arbitrary number of ">" in front, i.e. unquote

Fortunately, it seems that, in emacs as in perl, TMTOWTDI:

The way I find more obvious is to set ">" to be the comment character in
the mode you're using for editing. You can do that various ways, e.g.
(I'm sure there are others)

* with the sequence [M-x set-variable, comment-start, ">"]. Note the
  need to enter the quotes literally.

* set as a local variable in a file, e.g. append the text

> Local Variables:
> Mode:text
> comment-start:">"

The advantage of this approach is, when one wants to quote a region,
one thinks of quoting as commenting, and just does comment-region
(bound, perhaps by default, to M-#). This means also that

* unquoting        == C-u M-#
* quote to level=n == C-u n M-#

Here's how I do it:

Put a '>' in the first column of the first and second lines of the block
of text,  The hit C-q.

==================

As an alternative, I have this in ~/.emacs

(fset 'mailind "\C-a> \C-n\C-a")
(global-set-key [C-f8] 'mailind)

Then I can hold down C-F8 for as long as I need to prepend those '>' chars.

Another way I'm surprised no one has mentioned is just to select the
text using the region and then replace the regexp "^" with ">".

I used to do that kind of thing all the time when I mainly used vim.
Emacs's comment-region has made it much less necessary.
