Narrowing alternate lines

Narrowing alternate lines

[weber]

Folks,
I was checking out hidesearch.el and, even thought it is cool, I think
it could benefit from narrowing instead of using overlays to hide non
matched text (because narrowing makes text untouchable, basicly)

My question is: can you narrow a buffer like this:

hello
world
hello
world
hello
world

to become like this:

hello
hello
hello

.. or you can only narrow a single region ?

Thanks in advance,
weber

Yes.

But you can hide regions, by setting the invisible property.
