"[S]ometimes there is one really good answer to your search. And that's what led us to develop Instant Search
. . . As you type your search into the Instant Search box, it checks to see if there is a single, relevant answer for your query. If there is, that single result instantly appears on the page, just below the search box in a kind of 'speech bubble'. " (From Yahoo!)
This is a pretty neat little tool, one that just might save you a little time. As advertised, it instantly located "Madison weather" and a map of "975 Bascom Mall, Madison Wi"
It works for Yahoo! Shortcuts also, including sports scores, dictionary definitions, flight tracker, stock quotes, etc.
