: Customizing default action of "wheel" event. The value 0 means "Do nothing", 1 means "Scroll contents", 2 means "Go back or forward in the history", 3 means "Zoom in or out the contents". You cannot specify different action to vertical wheel operation and horizontal wheel operation because both deltaX and deltaY values can be non-zero same time. So, specifying different action doesn't make sense. | : Customizing default action of "wheel" event.
