Another trick I learned from an older HN comment is to create a .marks directory in your home directory and then add the following to your .zshrc

  export MARKPATH=$HOME/.marks

  function jump {
      cd -P $MARKPATH/$1 2>/dev/null || echo "No such mark: $1"
  }

  function mark {
      mkdir -p $MARKPATH; ln -s $(pwd) $MARKPATH/$1
  }

  function unmark {
      rm -if "$MARKPATH/$1"
  }

  function marks {
      ls -l $MARKPATH | sed 's/  / /g' | cut -d' ' -f9- | sed 's/ -/ -/g' && echo
  }

  function _marks {
      reply=($(ls $MARKPATH))
  }

  compctl -K _marks jump
  compctl -K _marks unmark

Now to remember a directory you type

  % mark <any_string>

and to jump to that directory you type

  % jump <any_string>

To list all your shortcuts

  % marks

Depending on the version of ls you might have to change the -f9 parameter to -f8 for marks functions
