Unfortunately I am rather a dummy when it comes to LaTeX, so
personally I would rather not go down that path.

AFAIK you can't put arbitrary text properties on the text out of the
box. But font-lock can execute arbitrary code when it finds a
match. This could be used to do this. It could also put appropriate
functions on the `point-entered' and `point-left' properties to
implement the auto-reveal/auto-hide stuff.

Should this be implemented as a minor mode?
