Sounds ok.

I don't think I've touched any of these definitions. And the debian
install I also used for testing, is completely new and unconfigured.

It's not a problem, at all.

^[[3~ (aterm, xterm, debian xterm, debian gnome-terminal)


PS: I noticed that the new gnome terminal has an option to choose between
3 sequences for BackSpace and Delete to be generated in the terminal
window. These three options are:
"Ascii Del" which generates "J"
"Escape Sequence" which generates "^[[3~"
"Ctrl-H" which amazingly generates "^H"

Ascii Del is the GTerm default for BackSpace, Escape Sequence for Delete,
which also seems to be the choice for plain xterms.

In nano on freebsd, TERM=xterm, both Ascii Del and Escape Sequence do a
"delete" (clears right), and Ctrl-H does a "backspace" (clears left).

As far as I remember, I've never seen the ^[[3~ sequence do a backspace,
in any TERM, so it seems to be the safest bet for a Delete. It's the "J"
sequence that tends to swap between Del or BS, in different TERMs.


Good luck. ;)
