If your pointing device of choice is a mouse (rather than a laptop trackpad), then you surely don’t just use its buttons – its scroll wheel must get quite a bit of use too. But what do you use it for, really? Wait, don’t tell me: For scrolling documents and webpages! If you’re an advanced user, you probably use it for zooming in and out, too, changing font size with a quick flick of the wheel. That’s all well and good, but it doesn’t even scratch the surface of what your mouse wheel can do.
