What do you get when you type cat<ENTER><SHIFT-TAB> in your shell prompt? (You can exit cat with <CONTROL-C>.) I get:

% cat
^[[Z

Then what do you get as output of print -n ${terminfo[kcbt]} | xxd? I get:

% print -n ${terminfo[kcbt]} | xxd
00000000: 1b5b 5a                                  .[Z

Both should match, as they do above.

Terminal :

cat                                                                                                                                                                                                                                                                                       
^[[Z

print -n ${key_info[kcbt]} | xxd                                                                                                                                                                                                                                                           
00000000: 1b5b 5a                                  .[Z

Console:

cat
^[

print -n ${key_info[kcbt]} | xxd

@oukemi hard to see the output of cat in the console. Please try cat | xxd<ENTER><SHIFT-TAB><ENTER><CTRL-D>

I get in my terminal:

% cat | xxd
^[[Z
00000000: 1b5b 5a0a                                .[Z.

(0a in the end is the line feed, which we ignore)

[ericbn]

Also, please note that this module will not be initialized if [[ ${TERM} == dumb ]]

[oukemi]

piped cat through xxd and still the same; on console I get :

cat | xxd
^[

echo $TERM
linux

[ericbn]

@oukemi end the cat input with <ENTER><CTRL-D> (that's D instead of C) instead of <CTRL-C>.
