One of the cool features in Mac OS X is the ability to “quick view” a file without actually opening it. If you have an item selected (highlighted) in a Finder window or on your desktop — or even a file embedded in an email message — just hit the spacebar and you’ll get a preview of the file.
If the file is a PDF document, though, it can often be formatted so that it’s too tiny to read anything. To magnify the document, click the Apple key — the command key with the curly symbol, next to the spacebar — and the plus symbol (+). That was easy, eh?
