# 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.
#          If you set your CDPATH to ${XDG_CACHE_HOME:-$HOME/.cache}/nnn/bookmarks
#          or to the value of BOOKMARKS_DIR, you can use it as a bookmarks replacement.
