                    Menu Pad

  Most gamepads have the following features:
  - Action-Pad 4 buttons in diamonds-shape (on the right side) NORTH, SOUTH, WEST and EAST.
  - D-Pad (Direction-pad) 4 buttons (on the left side) that point up, down, left and right.
  - Menu-Pad Different constellations, but most-times 2 buttons: SELECT - START.
  - Analog-Sticks provide freely moveable sticks to control directions, Analog-sticks may also
  provide a digital button if you press them.
  - Triggers are located on the upper-side of the pad in vertical direction. The upper buttons
  are normally named Left- and Right-Triggers, the lower buttons Z-Left and Z-Right.
  - Rumble Many devices provide force-feedback features. But are mostly just simple rumble motors.
