How do I disable a keybinding if I don't know what it is or what it's triggering?
I have my zsh key mode set to vi-mode, through bindkey -v.
To do a history search, I press Esc to get to "command mode", and then / to start the search. However, if I press them too fast, it does something else, but I don't know what! I assume Esc-/ is some keybinding, but I don't know what it is. How do I find this and turn it off?
After some searching, I've found the answer:
To discover what escape sequence the key combination is triggering, follow this excellent answer:
echo "CtrlVEsc/"
Which displays, for me, as: echo "^[/". CtrlV forces the following key to display as an escape sequence instead of being interpreted. So now we know we're trying to find what is bound to "^[/".
To list all zsh key bindings, simply execute bindkey with no args:
$ bindkey "^A"-"^C" self-insert "^D" list-choices "^E"-"^F" self-insert "^G" list-expand "^H" backward-delete-char ... "^Y"-"^Z" self-insert "^[" vi-cmd-mode "^[," _history-complete-newer "^[/" _history-complete-older ### <--- Here it is. "^[M" vi-up-line-or-history "^[OA" vi-up-line-or-history ... "^\\\\"-"~" self-insert "^?" backward-delete-char "\M-^@"-"\M-^?" self-insert So, having decided that I don't care about _history-complete-older, I'm just going to remove it. I added this to my .zshrc:
# Unbind the escape-/ binding because it gets triggered when I try to do a history search with "/". bindkey -r "^[/" If, instead, you just want to rebind it to some other key, you might use:
bindkey -r "^[/" bindkey "<some-other-key-combo>" _history-complete-older 
bindkey without other options: bindkey '^[/'. This question has two parts,
as mentioned in other answers
bindkey <key_combination> this will print the zle command related to the key combination
bindkey -r <key_combination> reference - http://zsh.sourceforge.net/Guide/zshguide04.html#l95
bindkey -rp '^' doesn't have any effect, but bindkey -rp '^[' and -rp '^X' do? It is probably
% bindkey '^[/' "^[/" _history-complete-older % or similar. And that's how you find out.
Also related is the KEYTIMEOUT setting, which indicates how long ZSH will wait to detect multi-key sequences, minimized by setting:
KEYTIMEOUT=1 If you're feeling super extreme, you can also remove all the ESC-something binds, so that ZSH has no multi-key sequences it will waste time waiting for following the escape key being pressed.
bindkey -rpM viins '^[' bindkey -rpM vicmd '^[' 
jk in vi insert mode to going to normal mode; you could as well have a little KEYTIMEOUT=20
