"How the Mouse Wheel Works" for Dummies

[dmm]

Dear friends,
I am an idiot. I finally figured out, just now, by accident, why people like the mouse wheel. (Keep in mind that I use a computer all day long.) For the benefit of all you other dummies out there, here is the exciting news: YOU DON'T HAVE TO KEEP SPINNING THE WHEEL TO MAKE THE SCREEN SCROLL! Just click the wheel once and move the mouse slightly either up or down, and the screen will scroll continuously. Move the mouse slightly in the other direction, and it scrolls the other way. WHEEEE! KEWL!
