Most of the time looking up words and proper spellings is as easy as typing a word right into Spotlight: input the word, and get a definition. This is great for trying to figure out if you’ve spelled a word right, or better yet, if you want to make sure you’re using the word properly. But, in this case you have to know the word you’re looking up. If you don’t, Spotlight isn’t much help in this capacity.
With Lion, Apple has introduced a new trackpad tweak that lets you bring up the dictionary, and look up words you don’t know from directly within the text. All you have to do is mouse over the word, then double tap with three fingers. Doing this should highlight the word yellow, and load the dictionary.
There you go. You no longer have to head to Google to look up that word that’s outside of your lexicon.
