Hi, this is a radiolist box. You can use this to
present a list of choices which can be turned on or
off. If there are more items than can fit on the
screen, the list will be scrolled. You can use the
UP/DOWN arrow keys, the first letter of the choice as a
hot key, or the number keys 1-9 to choose an option.
Press SPACE to toggle an option on/off.

  Which of the following are fruits?
