That's a good guide.  I started wondering about this because I wanted,
effectively, to apply folding levels to a subpart of an outline.  For
example, given 
A
   B
      C
         D
            E
      F
         G
         H

suppose I want to move to
A
   B
     C
     F
with the rest folded (where this is part of bigger outline, so I can't
just set the foldlevel globally).  Is there a good way to do that?

I was trying to get this working with some combination of folding
commands from B, but don't see a way around manually closing C and F.

Or could I hoist the relevant section, set the foldlevel, and then
revert?  When I try, the folding seems to be lost when I go back to the
main outline.

The general capability I'm looking for is setting the fold-level (like
\3 or ,,3 depending on prefix) for a suboutline.
