t_kB (shift tab) is not set when using st terminal

[phkbphkbphkb]

Hi,

I'm not sure if it is a bug in vim, but Shift-Tab is not working on my
machine. For example, it clears the line in command mode instead of
getting back to the previous completion.

I solved the problem using the following workaround (from
http://vim.wikia.com/wiki/Make_Shift-Tab_work):

:exe 'set t_kB=' . nr2char(27) . '[Z'

So the problem is that t_kB is not set by default.

I think it is related to the terminal used, because t_kB is not set on
st (https://st.suckless.org/) but is set on tmux (which has a different
$TERM).

Best regards,

And what is the value of $TERM and the option value of echo &term?

Best,
Christian

$TERM and echo &term are both st-256color.

Also I tested with "TERM=xterm vim" (but actually in st) and t_kB is
set. This confirms that the bug only happens with TERM=st-256color.

I think it is. I downloaded the st-0.8.1.tar.gz from there, extracted st.info, ran
tic st.info
TERM=st-256color vim -c 'echo &t_kB'
and it shows ^[[Z. (I ignored the tic warnings about unknown capabilities.)

Maybe your OS-level terminfo is old, try the above.

You are right. t_kB is set after running the tic command. It is probably
a distribution bug, then.

Thanks!
