Highlight any text on a Web page by holding down the left mouse button and dragging your cursor over the words. You'll see a blue box with an arrow. Click on that and you'll get a list of options.
If, for instance, you're highlighting an address, you can choose to map it on Google Maps, pinpointing the location. It can also do regular Web searches.
Let's say you're reading a column and you want to know more about the author. Highlight the author's name and choose search. You'll get search results for that person. You can also translate a phrase, e-mail certain text, and even blog with Windows live.
These options are called Accelerators by Microsoft. If you want to customize your options, highlight text, click the blue box, then select all accelerators--that gives you a bunch more options, including the capability to manage accelerators. Select that option. From there, you can disable or remove accelerators. Or click Find more accelerators and you'll go to a page where you can add many more.
