    • cd -
      will take you to the directory you were in before you last changed directory. This can be useful for 'flipping' between directories if you're working on something which involves two directories. [/*:m:1a9ovmqt]
    • cd (on its own)
      will take you back to your home directory[/*:m:1a9ovmqt]
