Directory bookmarking for bash

Question

Is there any directory bookmarking utility for bash to allow move around faster on the command line?

UPDATE

Thanks guys for the feedback however I created my own simple shell script (feel free to modify/expand it)

function cdb() {     USAGE="Usage: cdb [-c|-g|-d|-l] [bookmark]" ;     if  [ ! -e ~/.cd_bookmarks ] ; then         mkdir ~/.cd_bookmarks     fi      case $1 in         # create bookmark         -c) shift             if [ ! -f ~/.cd_bookmarks/$1 ] ; then                 echo "cd `pwd`" > ~/.cd_bookmarks/"$1" ;             else                 echo "Try again! Looks like there is already a bookmark '$1'"             fi             ;;         # goto bookmark         -g) shift             if [ -f ~/.cd_bookmarks/$1 ] ; then                  source ~/.cd_bookmarks/"$1"             else                 echo "Mmm...looks like your bookmark has spontaneously combusted. What I mean to say is that your bookmark does not exist." ;             fi             ;;         # delete bookmark         -d) shift             if [ -f ~/.cd_bookmarks/$1 ] ; then                  rm ~/.cd_bookmarks/"$1" ;             else                 echo "Oops, forgot to specify the bookmark" ;             fi                 ;;         # list bookmarks         -l) shift             ls -l ~/.cd_bookmarks/ ;             ;;          *) echo "$USAGE" ;             ;;     esac }

Also, have a look at CDPATH

A colon-separated list of search paths available to the cd command, similar in function to the $PATH variable for binaries. The $CDPATH variable may be set in the local ~/.bashrc file.

ash$ cd bash-doc bash: cd: bash-doc: No such file or directory  bash$ CDPATH=/usr/share/doc bash$ cd bash-doc /usr/share/doc/bash-doc  bash$ echo $PWD /usr/share/doc/bash-doc 

and

cd - 

It's the command-line equivalent of the back button (takes you to the previous directory you were in).
