KallOut for Firefox

KallOut's beta shows great potential for being the kind of unobtrusive, time-saving application we love. With two quick clicks, it turns text selections from a variety of Microsoft Office applications into search terms for a wide range of Web sites. In this way, selecting an unfamiliar term can populate a background search from Wikipedia or The New York Times, or find book titles or videos. It could help you quickly map a location or dig up public photos--all without opening a browser. Instead, KallOut delivers Web content to your application in a, well, call-out.

This goes for IE and Firefox browsers as well, where clicking on KallOut can launch a lookup within your tab and save you having to open up a new one. KallOut is so far off to a good start, but we'll keep a close eye on what comes next.
