Being probably MORE of a newbie than you. I have no
clue what hex number it creates. 

Somewhere in the back of my mind, from way too long
ago, I think I remember something about both control
and alt being sorta similiar to the shift key in that
they alter whatever the following keystoke sends as a
number. I too was surprised that crlt-alt-del was/is
coded as crtlaltdel in linux on that line. Oh, well,
just a newboo here 'opening foot inserting mouth'.

Please don't be offended by what I wrote, I didn't
have a clue as to how 'puter savvy you are. That is
what I wrote and tried not to offend anyone.

Nothing more is expected.
