You may have heard me rave about GuruNet (here is an example: GuruNet). I have used this service for years. It enables you to Alt-Click on any word or phrase when you are writing in any software application, reading any file with text or just surfing the Web and a window pops up with tons of information about the item. Here is an image that shows kind of what the window will look like:
Notice the amazing list of resources in the left column--and these are in addition to the Dictionary, Thesaurus, Sign Language, WordNet, Wikepedia, Encylopedia, Investement Information, Politics, Translations, Images, News and, depending on what you are researching, many other tabs that run across the top of the main window. It is the most useful on-line tool I have seen.
Well, the application is now FREE! I have added an Answers.com plug-in on the left column of this page. Try it out. Type something like "elephant" in the Answers.com entry field and press Enter.
If you like the service, download the 1-Click Answers software you will find at the Answer.com Web site and install the application on your computer. You will be Alt-Clicking in no time!
