Yes, we should bear that in mind.

I think that's true, but the lesser of the evils.
That is - even though the operation is, as you
say, not self-inverse, I feel that a step up
most naturally goes to the most recent
heading not containing the current one. So

Chapter 1
   Section 1
   Section 2
Chapter 2
   Section 1

from Section 1, we go to Chapter 1, not
Section 2. But the screen would start at the
foot of Chapter 1, so the bottom tear would
be visible, and it would be easy to go down
again to Chapter 2.

Of course one option would be to display
the name of what's above and what's below
in small type, or italic, or both, above the
tear -

      Section 2 - Whatever
   /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

Hmm. Does anyone like this idea? I'm not
sure.

We also need to think about the effect of
Find (this probably needs to open the source
to the entirety?) and indeed what Replace
does if the user globally replace Volume
with Section...
