You can use the four scrolling keys (KP8, KP2, KP4, and KP6)
    to expand, contract, and move displays, depending on the keypad
    state in effect. Thus, the keys do a SCROLL/UP, /DOWN, /LEFT, or
    /RIGHT, or a corresponding MOVE. You can press the GOLD key to
    make the operation to advance more than one line or column. The
    commands apply to the current scrolling display. Pressing KP3
    selects the current scrolling display from the display circular
    list.

    Four keys on the LK201 keyboard let you set the keypad state to
    DEFAULT, MOVE, EXPAND, or CONTRACT. The keypad state changes the
    definitions of KP8, KP2, KP4, and KP6. The meaning of all other
    keys remains unchanged.

    If you do not have an LK201 keyboard with the F17-F20 keys on it,
    you can get the same effect by typing the corresponding command:

                                  F17      F18      F19      F20
    SET KEY/STATE=DEFAULT  or  +--------+--------+--------+--------+
    SET KEY/STATE=MOVE         |        |        |        |        |
    SET KEY/STATE=EXPAND       | DEFAULT|  MOVE  | EXPAND |CONTRACT|
    SET KEY/STATE=CONTRACT     |        |        |        |        |
                               +--------+--------+--------+--------+

    For example, in the MOVE state (key F18), pressing KP2 moves the
    default scrolling display down by one character position, and
    pressing GOLD-KP2 moves the display down by a larger increment.
    The keypad remains in the MOVE state until you select another
    state, such as the DEFAULT state (key F17).
