Quick dictionary: command-control-D. Hold your mouse over any word in a document or webpage and watch as a mini-dictionary opens under the word. Continue to hold command + ctrl and move your cursor over other word and the dictionary will follow, changing to each word

 

 

 

 

Safari word finder: command-F. This is great to find a keyword. Try this on basically any webpage. Type the word you are looking for in the top right hand corner of your Safari window. The word will be highlighted for you, and you can click the right arrow to go to the next one and cycle through the entire page. This is useful on large pages to save from scrolling and searching the entire document manually. This will save you a lot of time!
