We likewise hook the Alt-F4 and some other keys.

Once you're not on serial, so it's possible to have multiple independent 
sessions coming from one PC, what is the advantage of working in screen? I 
seriously want to know.

I typically work with several Anzio windows open. Each one is 
independently positionable. I can Ctrl-tab between them in a cycle. If I 
wanted, I could assign macros to SWITCHTO a particular window by its 
title.

I don't think that's what META us. The link I found related to ncurses 
talked about turning on and off meta mode in the terminal, using the 'smm' 
and 'rmm' terminfo features. Neither of these capabilities exist in my 
terminfo entries for VT320 or VT420, for instance.

However, in the online help for YaST, on this page:
http://www.novell.com/documentation/opensuse111/opensuse111_reference/?page=/documentation/opensuse111/opensuse111_reference/data/sec_yast_ncurses_tasten.html

it says:
   Replacing Alt with Esc 
Alt shortcuts can be executed with Esc instead of Alt. For example, Esc+H 
replaces Alt+H. (First press Esc, then press H.) 

So you may be conflating :-)  Nevertheless, it looks like a good option 
for Anzio.
