We all know that we can scroll the page up and down by turning the mouse wheel to the desired direction.
Well, there?s another way to control that smoothly, by clicking on the wheel, which will display a double arrowed point, up and down. We can then move the mouse to the wanted direction. The more we vertically go farer from that double arrowed point, the faster the page scrolls.
Still we can use the mouse wheel to make the Web pages characters bigger or smaller by holding the key Ctrl pressed and turning the mouse wheel.
