Manage (remap) bindkeys with bindmap''#


Sometimes plugins call bindkey to assign keyboard shortucts. This can cause problems, because multiple plugins can bind the same keys. Also, the user might want a different binding(s), which will require a complicated, additional bindkey commands in .zshrc.

Zinit provides a solution to this problem – the ability to remap the bindkeys with a short ice-modifier specification with the bindmap'' ice.


# Map Ctrl-G instead of Ctrl-R for the history searcher.
zinit bindmap'^R -> ^G' for zdharma/history-search-multi-word

# Map Ctrl-Shift-Left and …-Right used by URxvt instead of the Xterms' ones.
# Load with the bindkey-tracking ↔ with light-loading for anything else.
# Could also separate the bindmaps with a semicolon, i.e.:
# bindmap'"\\e[1\;6D" -> \\e[1\;5D ; "\\e[1\;6C" -> ^[[1\;5C' \
zinit wait light-mode trackbinds bindmap'"\\e[1\;6D" -> \\e[1\;5D"' \
    bindmap'"\\e[1\;6C" -> ^[[1\;5C' pick'dircycle.zsh' for \

# Map space to regular space and Ctrl-Space to the `globalias' widget, which
# expands the alias entered on the left (provided by OMZ globalias plugin).
zinit bindmap='!" " -> magic-space; !"^ " -> globalias' nocompletions \
    depth=1 pick=plugins/globalias/globalias.plugin.zsh for \


As it can be seen, the bindmap'' ice has two modes of operation: normal and exclamation-mark (bindmap'!…'). In the first mode, the remapping is beind done from-key to-key, i.e.: bindmap'fromkey -> to-key'. In this mode, the given key is being changed to the second given key in the bindkey command that's being actually issued when loading the plugin.

In the second mode, the remapping is being done from-key to-widget, i.e.: bindmap'!from-key -> to-widget'. In this mode, the given key is being mapped to the given widget instead of the widget specified in the bindkey command, i.e.: instead of:

bindkey "^ " magic-space
bindkey " " globalias

the actual call that'll be done will be:

bindkey "^ " globalias
bindkey " " magic-space

(for the bindmap='!" " -> magic-space; !"^ " -> globalias' ice).

Using The UPAR, Etc. Shorthands#

There are four special values that can be used on the left side of the bind-map: UPAR, DOWNAR, LEFTAR, RIGHTAR. They'll match up arrow, down arrow, etc. So that it's possible to do:

zinit bindmap='LEFTAR -> ^F; RIGHTAR -> ^G' …

The benefits of using the UPAR, … shorthands is that they cover multiple possible cursor-key codes for each of the cursor key, so that they'll work regardless of the terminal being used.

Using bindmap'' In Light Mode#

When the investigation mode is on – i.e.: when the full loading mode is being used (default in the for syntax and when zinit load … is used) – then the bindmap'' ice works normally. In the non-investigation, i.e.: the light mode – activated when zinit light … or the light-mode ice is being used – the bindmap'' is unavailable, unless the trackbinds ice is specified, i.e.:

# With use of the light-mode ice and the for-syntax:
zinit light-mode trackbinds bindmap'^R -> ^G' for zdharma/history-search-multi-word

# With use of the classic syntax:
zinit trackbinds bindmap'^R -> ^G' for zdharma/history-search-multi-word
zinit light zdharma/history-search-multi-word
