I'm looking at a list of allowable keys in Sebastian's stuff, It includes:
EOT
NAK
DLE
... and such. I recognize those as contractions for 'negative
acknowledgement' and so on. However the doc says that these are all
supposta be defined in (n)curses.h and I can't find them. I'd like a
list so that I can add a few. Or are those codes something that zsh has
defined somewhere else? I don't find them as strings in the module src.

Hmm... *those* look like ASCII key names rather than curses key
definitions. Try "man ascii" or
http://man7.org/linux/man-pages/man7/ascii.7.html
pws

Thanks Peter, yeah I know they're ASCII, but there seems to be a
conflict, or one of those situations where one has no idea who owns a
key. I tried to add 'EXT' (^C of course), but it wouldn't take. The
ones I mention show up in my editor as bright white boxes--clearly they
are recognized as special--but no luck with EXT (tho I could capture ^C
with " ${\x0A} ").
case "$NKEY" in
(${\x0A}) ACTION='QUIT'; REPLY=-1 ;;
($'\n') REPLY=$IN[currentE]; ACTION='' ;;
($'\b'|\x7f|BACKSPACE) SEARCH_BUFFER="${SEARCH_BUFFER%?}" ;;
(ETB\x17) [ "$SEARCH_BUFFER" =
"${SEARCH_BUFFER% *}" ] &&\
" ETB " had to be added ... it didn't actually paste over, because I
understand that it's some symbol, not literal text. Point is that " ETB
" 'works', but not " EXT ".
So, I'm wondering who/where I'm not getting control of ^C via 'EXT' in
zcurses. Also, ^C behaves very strangely. " zcurses input " treats ^C
differently depending on whether the call is inside a function or not.
In some situations it creates a repetition of the previous keystroke.
Sometimes it exits the program, sometimes it's just ignored. I was
hoping that there'd be some zcurses/ncurses list of all accepted keys,
where I'd hope to see some mention of the ASCII acronyms and in
particular what's going on with ^C. I'd suspect that something else,
like the terminal, is getting in the way, but, again, I can handle ^C my
way with " ${\x0A} " so it seems to be under my/zcurses control.
