Often times I'll have an e-mail message with some code in it, or code
with some text in comments.  Is it possible to highlight a region and
tell Emacs to (use ___ mode instead of ____ mode)? 

Thanks in advance,

Dan

The simplest way to do this is to use 'clone-indirect-buffer' (C-x 4 c)
and use A-mode in the original buffer and B-mode in the cloned buffer.
Put the two buffers in adjacent windows and switch between them when you
want the features of the other mode.  See the Info node (emacs)Indirect
Buffers.

There are third-party add-ons that claim to support multiple major modes
in the same buffer (I don't know how they work, but if they have any
sense they will work by automatically switching to the appropriate
indirect buffer depending on the value of point).  See
http://www.emacswiki.org/cgi-bin/wiki?MultipleModes for a selection of
possibilities.

Wow, that is really cool!  Especially if you narrow each buffer to show just
the parts relevant to that mode.

As in <URL: http://www.emacswiki.org/cgi-bin/wiki.pl/IndirectBuffers>?

Now, if only there were a way to have a "super-buffer", created
out of multiple other buffers, mmm-mode would be a lot easier to
write :).

This method seems to partially work.  I can clone an html buffer (in
html mode) and switch to the cloned buffer and issue M-x text-mode.
The modes are correct for each buffer however they seem to share
fontification.

So if I do M-x font-lock-fontify-buffer while in the text-mode buffer
I see the changes in both.  Same if I issue the command in the
html-mode buffer... the text-mode buffer then gets fontified for html.

I'm using cvs, so perhaps it's just my version.  If this is a known
limitation of clone-indirect however, then it wouldn't be as useful a
method for multiple modes (at least for me).
