I try to keep my scheme in included files containing not much
else. (That's easy for me as most of it is snippets I have garnered
here and elsewhere.)

But one thing I do keep handy is a single key defined to <press TAB>
and <move forward one line>. That way, I can move to the top of the
file and just hold down that key to tidy up the whole file.

Way back when spontaneous "narrowing" used to happen to me, I would
do this quite often. Whether it had any real effect, I don't know.
It might just have been cargo cult science.

Cheers,
David.
