Speaking of Terminal, the second quickest way to add Terminal aliases to ~/.profile is

mate ~/.profile

Which will open it up in TextMate. The quickest route would be using the nano text editor

nano ~/.profile

But then you got a text editor in your Terminal, which prompts Xhibit to show up

Yo dawg, I herd you like black windows, so I put a text editor in your Terminal so you can develop while you develop.
