Revealing Hidden PDF Services in Mac OS X 10.2.4 In Mac OS X 10.2.4, Apple quietly added the ability for users and developers to enhance the standard Print dialog with custom PDF-handling options. To enable it, just create a folder '~/Library/PDF Services' and populate it with aliases to applications, scripts, Unix tools, or other folders. Those items then show up in the Print dialog as optional handlers for Mac OS X's built-in 'Save as PDF' feature. Drop a renamed alias to your mail client in there, and you've added convenient 'Send PDF as Email' functionality to every application." [via Studio Log]
