The sketch assumes that the joystick resting values are around the middle of the range, but that they vary within a threshold. The pushbutton allows you to toggle mouse control on and off. As an option you may connect a status LED to pin 5 that lights upwhen the Arduino is controlling the mouse. A second pushbutton may be connected with another 10k ohm pulldown (to GND) resistor to D3 to act as the left click of the mouse. -**NB: When you use the Mouse.move() command, the Arduino takes over your computer's cursor!
