Alfred Free

alfredapp.com Purely as a Spotlight alternative, Alfred immediately won our affection because it displays keyboard shortcuts ( and a number) next to its top search results. It provides greater specificity than Spotlight, so you can enter ‘define’ followed by a word to pull up that word’s meaning and nothing else. And there’s much more, including a clipboard history, the ability to buffer multiple files to take action on all of them at once, and, with the paid-for Powerpack, taking direct action on looked-up contact info.
