On my slackware-current box, with nano 1.3.0-cvs in an xterm under
XFree86 4.3.0, I've been able to reproduce the second and third of these
a few times in a normal 80x24 terminal and with extra rows, and the
fifth one once with extra rows (although I think the fifth might be an
xterm problem).  I'm looking into it.

Good.

Unfortunately, since shift-[arrow key] seems to either act just like
[arrow key] or generate the same escape sequences as Ctrl-[arrow key] in
xterm, Eterm, and the Linux console, it most likely can't be implemented
properly.  nano 1.3.x doesn't interpret escape sequences (except for
one, in order to deal with some FreeBSD breakage), because escape
sequences in general are often horrendously incompatible between
different terminal types, and for that reason it's difficult to avoid
breakage if one relies much on them.

As for your other suggestion, I'm not sure what you mean by ^C ^X ^P
block operations.  Would you please explain?

Thank you.
