I'm assuming everyone knows about using "Ctrl-r" to search through your BASH history.
For example, to search for all your cd commands press "Ctrl" and "r" at the same time followed by "cd". That will show your last cd command. To see the previous one press Ctrl-r again. Keep pressing Ctrl-r to do a reverse search through all your cd commands.

Horses for courses. 😃
Of course, you can do that, too. However, "Ctrl-r cd" is only 5 keystrokes, so a bit faster.
