Lookup words in Preview.app

[ykarmi]

Hi,
I was wondering if there was a way to lookup words in a PDF opened in Preview.app. What I'm looking for is double-clicking a word (or similar functionality) and having the definition pop up. This would be useful when I read PDF's and stumble upon an unfamiliar word.

Is there such an option/plugin?
Thanks!

No plugin that I know of, but you can use the built in dictionary and thesaurus that included with OSX to search for words you don't know.

Or right-click on the word and select Look Up in Dictionary.
