A little bit of lunchtime reading can be a great way to take a break from the work day.
Rather than getting messy fingers all over the keyboard and mouse, try getting an automatic scroller to do all the hard work for you.
There are a number of different plug-ins available for both Firefox and Chrome that automatically scroll down large chunks of text as you read. There are also speed adjustments depending on how quickly or slowly you like to read. For Firefox, try ScrollyFox, which is available from the Mozilla add-ons page; and in Chrome, Auto Scroll from the Chrome Web Store.
