"narrow": `# Implementation of location, history and lastcmd mode using the new
# -narrow-read mode. One advantage of this is that it allows the
# execution of arbitrary hooks before or after each mode.
#
# Usage:
# use narrow
# narrow:bind-trigger-keys
#
# narrow:bind-trigger-keys binds keys for location, history and lastcmd
# modes. Without options, it uses the default bindings (same as the
# default bindings for edit:location, edit:history and edit:lastcmd),
# but different keys can be specified with the options. To disable a
# binding, specify its key as "".
# Example:
# narrow:bind-trigger-keys &location=Alt-l &lastcmd=""
# Hooks
# Each hook variable is an array which must contain lambdas, all of
# which will be executed in sequence before and after the
# corresponding mode.
# Example (list the new directory after switching to it in location mode):
# narrow:after-location = [ $@narrow:after-location { edit:insert-at-dot "ls"; edit:smart-enter } ]
