FISH shell VI keybindings with ctrl-<arrow> word navigation

README.md

1. enable VI mode

   fish_vi_key_bindings
   

2. restore the word navigation keys I'm used to in insert mode

   cat << EOF > ~/.config/fish/functions/fish_user_key_bindings.fish
   function fish_user_key_bindings
     bind -M insert \e\[1\;5C nextd-or-forward-word   # ctrl-right
     bind -M insert \e\[1\;5D prevd-or-backward-word  # ctrl-left
     bind -M insert \cK kill-line  # bring back emacs style <C-k> in insert mode
   end
   EOF
   

Thanks to https://superuser.com/a/1092277/384058 for how to get the keys to be bound on terminal startup.

Thanks to https://unix.stackexchange.com/a/76591/68885 for some useful tips on finding keycodes.

fish_key_reader is a useful tool to figure out a key sequence.

You can use

sed -n l

...to dump the escape codes when you press keys.
