As is it is just a command. You can bind that command to a key of
your choice.

Doing it automatically is an interesting question. I don't know how, but
maybe there is a way in TPU - an "on something changed event". I don't
think anyone wanted to do that back then (late 80's early 90's), but
with todays CPU's then why not.

It definitely does not use status line. It just highlights and when
you scroll down you can see it as highlighted. That would
obviously not work with the automatic process you envision above
and VT where scrolling change current position.
