title: Mouse Wheel Scroll - How can I capture the time interval between start and stop of scrolling?
body: <p>Is there any way to capture the time interval between mouse wheel scroll start and stop?  Actually I want to capture the interval between the scrolling start and stop when I very quickly scroll the mouse wheel.</p>
  
  <p>I have already looked at MouseWheel event but it don't fulfill my requirement. In senes that it always gives a value of Delta 120 or -120 but i want to call a function depending on the speed of the mouse scroll for example when i scroll the mouse normally i want to perform function 1 and when i scrolled the mouse very quickly i want to perform the function 2. In other words is there any way to distinguish between the mouse scroll high and normal speed. </p>
  
  <p>Any advice will be appreciated.</p>
