8. Do a Spotlight search directly within Safari
If there’s a word, a name, or some other string of text on a web page that you’d like to dig up some info on, there’s an easy way to do it without ever leaving Safari.
Just tap, hold, and drag the selection handles around the words you want to look up, then tap the aptly named ‘Look Up’ button in the black options bubble that appears. When you do, an overlay window with universal ‘Spotlight’ search results will appear, including hits like word definitions, recent news stories, Wikipedia articles, relevant reviews, and (not surprisingly) matches from the iTunes Store.
