[pdftex] Full screen online pdf

[John Culleton]

My question relates to pdfs created for on line
viewing using Acrobat Reader.

There are ways to make a pdf appear full screen and
without the usual navigation aids etc. using either
pdftex or Context. However one can maneuver out of
full-screen mode with an alt-esc key combination.

My question is: can one trap the alt-esc in some
way so that the key combination would no longer 
restore the navigation aids, thumbnail and bookmark
tabs and so on. Of course an exit button would be
needed on every page.
