lilypond-book and include using emacs

[Paul Scott]

This is really an emacs question but maybe some of you know this:

I am just starting with lilypond-book to try to get my headers to do 
things that may or may not be possible with just lilypond.  I have the 
example from the tutorial working but need to add an include file to the 
tex file I am editing with emacs.  emacs in tex mode wants to change 
this to `` .

Can anyone tell me how to get the " without using a second editor?

TIA,

Paul Scott
