class BBS::Terminal::Question

The question itself, in plain ASCII capitals: the faces, a digit each, and the guess as the default. A key only picks, RETURN takes it; a changed pick prints the prompt again on a new line.

Constants

TAKE_KEYS: The keys that take the pick.
UNPICK_KEYS: The keys that take the pick back.
