Adobe Systems has released the tenth version of the venerable Acrobat: Acrobat X (pronounced “ten,” not “ex”). Be prepared for culture shock: the interface is completely revamped. Not the “we moved some menu items around to keep you on your toes” you’ve seen in previous versions, but an utterly different environment. Like the “re-imagining” of recent Hollywood sequels, this one bears little resemblance to its ancestors.
As I explore more deeply, I’ll post more. But, for now, here’s how to find the full-fledged User Guide. From the Help menu, choose “Adobe Acrobat X Pro Help.” The Adobe Community Help application launches (as of CS5, the Help files appear in the Help application, not in your Web browser). Look for the PDF icon in the upper right corner of the interface, and click on “View Help PDF.” Once the PDF opens within the Help app, click the little floppy “save” icon to save the PDF to your hard drive.

Click the highlighted link to load the User Guide PDF, then save the file to your hard drive.
