3# Handle bookmarks. This uses the static named directories feature of
4# zsh. Such directories are declared with `hash -d
5# name=directory`. Both prompt expansion and completion know how to
6# handle them. We populate the hash with directories.
7#
8# With autocd, you can just type `~-bookmark`. Since this can be
9# cumbersome to type, you can also type `@@` and this will be turned
10# into `~-` by ZLE.
