One of my favorites I learned from this thread was pushd/popd. This is a method for changing directories but also logging where you just came from so you can easily jump back. In the following example I will jump from my home directory to / to /Users and then use popd to reverse in order through the same directories.

$ pwd /Users/Bryan $ pushd / / ~ 
$ pwd / $ pushd Users /Users / ~ 
$ pwd /Users $ popd / ~ 
$ popd ~ 
$ pwd /Users/Bryan 
$
