I've been using cbreak mode since day-1 or at least day-1.5

It seems clear at this point that layers running "below" ncurses are 
limiting its usefulness by taking over certain keys for their cutsie 
menus and so forth.  I had hoped that there was some even-lower-level 
Linux system facility that nurses could use to get some control back but 
apparently not, apparently I'll need to go on some quest to find out who 
the heck "owns" the terminal and see how things can be dealt with more 
usefully.

I might need to entirely abandon ncurses as useless for my purposes and 
work through the fugliness of html since at least browsers serve up a 
level of cross-system consistency.  But I really don't want to give up 
the key-by-key responsiveness that ncurses in cbreak mode provides, and 
I really don't want to deal with the security issues of having a local 
apache server involved in a lower-level utility's interface.

Thanks to all those who attempted to help.
