How about pushd and popd? Those who don't know UNIX commands are condemned to re-invent them.

BartonA nice compliment to this is
set | grep '^[a-z]'
Since bash variables and the body of all shell functions do not start with lower-case letters, this leaves a manageable list to look through, to remember which variables you set. If you start them all with 'a', they'll sort to the top.
AdrianTM: yes, pushd and popd have their place, as does 'cd -'. I find pushd and popd rather cumbersome, perhaps that's just because I don't know them very well. This tip is very light weight; I will definitely be adding it to my .profile.
