I'm having a couple problems with basic command line stuff in the terminal of Mountain Lion.

<kbd>control</kbd> + <kbd>D</kbd> does not exit Python as it does in Lion; instead it splits the screen.

Meanwhile, I also haven't figured out how to continue writing after having viewed the contents of a text document - the terminal doesn't allow it.

> Hello hello hello! ex12.txt (END)

So far, no matter what I push after this, I get a nasty little beeping sound
