Example 2: Programming two keys to control the motion of an additional unit:
You can program two keys to control the motion of an additional unit. In the following sequence of
commands, key 1 and key 2 are programmed to control unit 5, an additional unit beyond units 2, 3, and 4
which are controlled by joystick manipulation. After executing this sequence of instructions, key 1 can be
used to move unit 5 in the positive direction, slowly at first, but faster if you hold the key down for longer
than 1 second. Key 2 will exhibit the identical behavior but with motion in the negative direction. When
either key is released the motion will stop. Assuming that the joystick is unit #1, the programming sequence
is as follows:
