I'm sorry: what is an "overlay"? Do you mean the standard NB .kbd? I don't
use that
.
 -- take a look at the
[Startup] stanza in NB.INI (in [NBroot]\users\default). Alt-C is among the
overlays so loaded.

When I CAll that, I get an error message saying: error writing to
c:\nbwin\users\default\nb.ini, but I'm not sure that means anything.
 
You can't promiscuously use the Alt-letter Save/Gets --
not unless you elect to *not load* the NB overlays.
How do I not load them?

 (That's what I do, but
that also disables a ton of Toolbar functionality, so unless you
understand the
consequences and are prepared to use NB merely as a word processing engine
driven from the CMline, then... don't do it. I mean, obviously, if you like to
make Outlines, then the NB Frameworks tool is going to be helpful -- and
you'll
need the overlays!)

My decision here depends, clearly, on coming to understand what an
"overlay" is.

I don't know what "Ctrl-Shift 00" does and neither does anybody else.

That's how I get ascii characters. It's the R0, R1, etc. But I think that
means 3-byte codes on the Command line.
 
What
does "00" mean? If you're trying to search for char zero, it would be "0" --
single zero -- if it worked. But no factory service can find Ascii-zero; you
can do it via U2, however, e.g. frame CHECK32-127 accepts an optional argument
to search for a 1-byte character by number, even if it is embedded within a
3-byte character:
 CHECK32-127 0 <==search for 1-byte zero
So you could open your KBD file, position cursor at TOF, and run this
frame, to
see if there is indeed a 1-byte zero in the file (most unlikely). To do this,
you need a refresh of U2 v119 that has been posted today.

Another reliable way to find zeroes in files is to LIST the file (with
LIST.COM), toggle into hex mode (Alt-H), then search (F, then F3 on subsequent
"find agains") for "{space}00{space}".
That's indeed exactly what I ended up doing.
