Scrollbars. Ever heard of them? They’re pretty cool. Click and drag on a scrollbar and you can move content around in a scrollable content pane. I love that shit. Every day I am scrolling on my computer, all day long. But the scrollbars are getting smaller and this is increasingly becoming a problem...
Many mouse wheels act as a button as well. Hold the button down while moving the cursor up or down to scroll effortlessly. The further the distance you move the cursor, the faster it scrolls.
