The wheel event structure is used to store a wheel rolling, it facilitates processing of the wheel rolling and passing to other libraries like Toolkit.
There is a key modifier which relates to keys like Alt, Shift, and Ctrl functions are supplied to check if they have been pressed when the wheel is being rolled.
