# Description: 'cd' to the directory from CDPATH
#
# Details: If the CDPATH environmet variable is not set, the default value of
# ${XDG_CONFIG_HOME:-$HOME/.config}/nnn/bookmarks will be used.
# You can create this directory and fill it with symbolic links to your
# favorite directories. It's a good idea to add it to CDPATH so that it
# could also be used from the command line outside of nnn.
# The fzf search is done on the directory basename (the first column).
#
# This plugin is an extended version of the bookmarks plugin.

# Shell: POSIX compliant
