MOVE DOWN

 Moves the cursor down one line at a time.

 o  If the cursor is FREE, it moves down in the same column.  If the cursor
    is BOUND, it moves to the corresponding position on the next line, if
    any, following the shape of your text.  For example, from the end of a
    line longer than the next line, the cursor moves to the end of the next
    line.

 o  If you are at the end of a buffer, the cursor does not move unless the
    buffer is less than the window length and the cursor is FREE.

 Keys:  EVE defines the DOWN arrow key as MOVE DOWN.
        The VT100 keypad also defines KP2.
