– One of the things which bugs me with many sites is that you may have to do lots of scrolling to read the text. If you just scroll with your mouse scroll wheel it may only move three lines at a time. One way to fix that is to get into the Control Panel – Mouse – and change the wheel settings. I’ve got mine so that any time I scroll the wheel by one click it moves down one screen.
If you want to zoom in on a website, hold down the CTRL key and use the scroll wheel again. If you want to zoom out, scroll in the opposite direction.
