The : stagger ""; command will place press_any_key events between paragraphs, but not after the final paragraph (if there is just one paragraph, there are no press_any_keys). For large amounts of dialog, without any beeps inbetween, stagger is the lazy way to do it.
Agree with Gareth. Returning to the command line after a final press_any_key without a screen refresh just feels wrong to me.
