I've recently switched to vi-mode in my zsh and there is a feature from emacs-mode that I cannot find how to do in vi-mode. The feature is browsing history by lines starting by something I've already typed. For example if I type vi and press or then I browse through my recent commands starting with vi. Is it even possible with vi-mode?

emacs-mode and vi-mode are only different presets of key bindings. Any widget can be bound in any mode.

The widgets in question here are history-beginning-search-backward (presumably for ) and history-beginning-search-forward (for ).

To bind them to the up and down keys in vicmd mode, you just need to run

bindkey '^[[A' history-beginning-search-backward
bindkey '^[[B' history-beginning-search-forward
  • Note 1: This overwrites the default setting for those keys.
  • Note 2: ^[[A and ^[[B may not be the correct codes for your terminal.

    • either Find the correct ones by pressing Ctrl+v followed by the key in question.
    • or make use of the associative array terminfo to retrieve the correct binding (my thanks to Stéphane Chazelas for his comment on this):

      bindkey "$terminfo[kcuu1]" history-beginning-search-backward
      bindkey "$terminfo[kcud1]" history-beginning-search-backward
      

      kcuu1 and kcud1 are the capability names for and , respectively. You can get a list of possible capabilies and their names from the terminfo(5) manpage (man 5 terminfo). The associative array terminfo uses the names from the "Cap-name" column as keys.

    See also $terminfo[kcuu1] to get the sequence for the Up key from the terminfo database. – Stéphane Chazelas Jun 8 '16 at 16:15
