 def scroll(clicks, x=None, y=None, pause=None, _pause=True):
 """Performs a scroll of the mouse scroll wheel. Whether this is a vertical or horizontal scroll depends on the underlying operating system. The x and y parameters detail where the mouse event happens. If None, the current mouse position is used. If a float value, it is rounded down. If outside the boundaries of the screen, the event happens at edge of the screen. Args: clicks (int, float):
 The amount of scrolling to perform. x (int, float, None, tuple, optional):
 The x position on the screen where the click happens. None by default. If tuple, this is used for x and y. y (int, float, None, optional):
 The y position on the screen where the click happens. None by default. Returns: None """
