Hi Benjamin,
I want to summarize, what I have found:
I am using vim under linux -- gvim is used very very very seldom.
The TERM variable is set to:xterm-256color.
I am using utf-8.
First experiment:
Using ALT-BS under zsh works. bindkey -L | grep backward-kill-word
gives me:
bindkey "^W" backward-kill-word
bindkey "^[^H" backward-kill-word
bindkey "^[^?" backward-kill-word
which seems to be the same as what you see with your zsh...
Second experiment:
Opening vim from this zsh/terminal and
doing CTRL-k ALT-Backspace in insert mode gives: <nothing>
Same goes for CTRL-v
No trying to insert ALT-backspace on the commandline of vim:
This puts me back to the buffer, leaving the commandline.
=> There is "something", vim recognizing, otherwise it stay
in the commandline. But it seems not enough to be recognized
as a valid keystroke.
Now trying <ESC><BS> as keystrokes, same experiments:
In insert mode, the <ESC> key puts me back to command mode
instantly.
Commandline: Same scenario.
In /etc/inputrc (this is the only inputrcon this system) there is set:
set input-meta on # Enable Meta input with eighth bit set
set meta-flag on # Synonym for the above
set convert-meta off # Do NOT strip the eighth bit
set output-meta on # Enable Meta output with eighth bit set
Regarding to the ctrl-v- and ctrl-k-experiments there would be no
hope to get any mapping with ALT-backspace working.
From what can be acchieved with zsh and regarding to the inputrc
it /should/ work nevertheless.
Finally I put a
nmap <esc><bs> db
into the .vimrc
and...it works! After all I dont know why.
Final thing I want to fix (help appreciated ;)
is this:
When I put a "imap <esc><bs> :normal db<cr>"
into .vimrc and restart vim to execute ALT-backspace
in input mode it prints :normal db at the cursor
position and jumps to the next line.
Is there a way to get it working in input mode also?
Best regards and have a nice sunday!
mcc
