CleverKeys

This handy freeware lets you quickly look up a selected word from virtually any program. Unlike similar browser add-ons, CleverKeys doesn't integrate with Windows or place an additional toolbar on your browser window. Instead, it's accessible using hot key combos. Its tabbed, easy-to-use interface references a word in Dictionary.com, Thesaurus.com, and Amazon.com. We like that users are able to add their own URLs to look for definitions associated with the selected word. We were amazed by how CleverKeys was able to look up words from Notepad, Microsoft Word, WordPad, Outlook Express, and more. Although the program is categorized as an Internet Explorer add-on, we were glad to find that it also works for Mozilla Firefox. With that said, CleverKeys makes a nice pick for anyone who needs to quickly pull data off the Web.
