No mention of ZSH directory stacks yet? http://www.acm.uiuc.edu/workshops/zsh/dir_stack.html

Some helpful aliases to manage them:

alias 1='cd -1'

alias 2='cd -2'

alias 3='cd -3'

alias 4='cd -4'

alias 5='cd -5'

alias 6='cd -6'

alias 7='cd -7'

alias d='dirs -v'

alias h='history'

alias j='jobs'

Just one of the many reasons to use ZSH.
