Firefox: Quick searches and keywords

Its one of the most useful and rarely used feature of Firefox. Try this, in Firefox, key up to the location bar (Windows: Alt-D, Mac: Cmd-L), type dict eschew and hit Enter. You’ll be automagically transported to the Dictionary.com definition of “eschew” (to avoid, shun). That’s a Quick search in action.
