Explanation

The MouseWheelDownImage event is generated when the mouse wheel is rolled down. Any code written in this event will execute whenever the mouse wheel is rolled down. Furthermore, by using the Shift parameter, you can determine whether another mouse button was pressed at the same time the mouse wheel was rolled down. In this way, you can write different code that executes if the left mouse button is pressed while the mouse wheel is rolled down or if the right mouse button is pressed while the mouse is rolled down, etc.

Note: The Direction parameter returns the value set in the MouseWheel property.
