I love Quick Look, easily the best feature Apple’s added to the Mac OS in years. But sometimes when I Quick Look a PDF, the text is too small to read. Can I zoom in on that, or do I have to just open the PDF in Preview and zoom in that way?

Quick Look does have a couple of zoom controls, but they only work on PDFs and images. We tried them on a Word doc (Quick Look shows the text sooooo tiny) and got nothing. But if you’re using Quick Look to view an image or PDF, press Command-= (equals sign) to zoom in, and Command-- (hyphen) to zoom back out again.

Zooming in on a Quick Look window of last month's masthead. Yep, they spelled my name right.

While we’re on the subject of Quick Look keyboard shortcuts, remember that you can press the spacebar to enable Quick Look, Escape to exit, and if you’re viewing multiple files in Quick Look, you can use the right and left arrows to navigate through them. If you’re looking at a file from a long list of files in a Finder window, the up and down arrow keys will Quick Look the file before and after the current file, respectively. Now that’s quick.
