I'm always looking for ways to work faster, and sometimes I discover that people don't know about some simple tricks I've used for years.
For instance, suppose you're on a window with a scroll bar (the bar at the right side). Most people will click on the arrow at the bottom (red arrow). But that only scrolls down a line at a time. You either have to click quite a few times, or hold down and wait.
It's much better to click on the scroll bar (green arrow). This moves down a screen at a time. Another quick way is to click and drag the slider (at the top of the scroll bar). Another advantage of these two methods is that the spot is a much easier target to click on than the down arrow. These also work moving up, of course.
And here's another tip when your browsing the web: use your spacebar. This will scroll down a page at a time, much faster and easier than using the scroll wheel on your mouse or the scroll bar.
