Quicklook is Mac OS X’s way of letting you see any file up close with just a tap of the spacebar. When you’re in the finder, for example, and you click on a photo, you can hit the spacebar and see the photo large and up close, making it easier to figure out which images to toss, and which to save. You can do the same with any supported text file, like an rtf, doc, or pdf file to see what’s in it at a glance.
But what if you want to copy a quick bit of text to paste somewhere, like an email? Instead of opening the file, waiting for the associated app to load, and then copying the bit of text, give this trick a shot.
