When we're browsing the Internet, it's easy to come across a word, a phrase, an address or similar where you're simply stumped. Of course, it's not too difficult to open another browser window (or tab) and simply check Wikipedia or Google. But what if they don't always give you the answer? You can keep on looking. Another solution is a device which would enable you to perform a custom check or search, depending on your choice, from the page you're currently browsing.21 Sep 2008
