Place your terminal, prehensile part of the upper limb on to the palm-sized, button-operated pointing device and relocate the movable, sometimes blinking, symbol to the piece of cloth attached at one edge to a staff that is colored green. Using the terminal member of the hand closest to the short, thick, inner digit of the human hand, act upon the leftmost pointing device button with steadily applied weight or force, making a slight, sharp sound.
