I'm using emacs 21.3.1 on Windows XP SP2.  I have been a long-time (27
years now!) user of emacs, and still love it.  One thing I really like
about the Visual Studio .NET 2005 editor is that it has the ability to
contract and expand sections of code or comments through use of the '-'
and '+' controls to the let of the code section.  Is there a package for
emacs that can do that?  I know about narrow-to-region, but that only
works for a single region.  Anything that will allow multiple cases of
something like that?
