That is odd.

$ cat /var/log/packages/ncurses-6.1_20180324-x86_64-3 | egrep
\(ncursesw\?\|tinfo\)\.so
lib64/libncurses.so.6.1
lib64/libncursesw.so.6.1
lib64/libtinfo.so.6.1
usr/lib64/libncurses.so
usr/lib64/libncursesw.so

Maybe the difference is due to some patching in the Ubuntu version?
Your versions of 6.1-1ubuntu1.18.04 don't indicate which incremental
version they're based on, and, if I recall correctly, Slackware's
philosophy is to patch original sources as little as possible, whereas
Ubuntu is more liberal when it comes to patching.

In yours, the ShortcutsNoHelpkey, ShortcutsNoMenukey, and
ShortcutsNoMnemonics options would affect key interpretation, but I
think they just keep certain keys from being intercepted by the terminal
instead of nano, so they wouldn't be causing this problem.  If they
correspond in the GUI to Edit -> Preferences... -> Advanced -> the three
toggles under Shortcuts, this should be the case.

(For the record, I also think it's a problem that you have to manually
edit xfce-terminal's configuration file to get a blinking cursor, and
that there's no GUI equivalent for it, but that's definitely off-topic.)

I'm not sure either, but I don't think it affects key interpretation.

Good to know, but I don't think it affects key interpretation either.
