pushd and popd forever
Becoming tired of typing paths repeatedly in the terminal, I realized that I should be using pushd and popd to be navigating directory structures. For those uninitiated, pushd changes your current directory in a similar fashion to cd but additionally adds the former directory to a stack. You can later return to the former directory by executing popd, popping it from the directory history. Unfortunately, the commands pushd and popd both require at least twice as many characters to type as cd and additionally come with the overhead of having to learnt o use a new command instead of something that is nearly instinctual....
