# keymap/set Bind a chord to a command name, replacing any prior binding. Publishes a change event on the `"keymap"` pub/sub topic. Returns the command as given. ## Syntax

[keymap/set "app" "mode" "chord" $command]

## Parameters - `app` — app name (string or keyword) - `mode` — mode name (string or keyword) - `chord` — canonical chord string (string or keyword) - `$command` — command name; any stringifiable value, stored in stringified form ## Examples

[keymap/set "editor" "vi" "ctrl-s" "cmd-save-all"]    # → "cmd-save-all"
[keymap/set "log" "default" "f" "cycle-filter"]

## Returns The command value exactly as passed in (not its serialized form). `%Err{:message}` when a string/keyword argument is missing, the command is missing, or it is not stringifiable. Subscribers on `"keymap"` receive `%{ :app :mode :chord :value :old }` under `:data`. ## See Also `keymap/unset`, `keymap/reset`, `keymap/get`
