Apple's OS X Mavericks offers more than 200 new features, many of which are overshadowed by marquee additions like Finder tags and iCloud Keychain. I've fallen in love with a lesser-known feature that's already saved me lots of time: Export as PDF from the File menu.
Previously, you could convert a file to PDF by opening a Print dialog, selecting Save as PDF and then choosing a destination. Now it's even easier.
Simply select Export as PDF... from the File menu of a supported app and presto! Instant PDF. You can even add a tag while you're at it. Note that some apps aren't supported. For example, the option is there in Safari, Text Edit and Mail, but not in Microsoft Word.
