Today, Microsoft made available 9 free Quick Start Guides for Office 2013.
“These printable guides contain useful tips, shortcuts, and screenshots to help you find your way around”.
On Windows 8, you can open and view these guides in the Windows 8 Reader app without any additional steps. If you’re using Windows 7 or earlier, you’ll need to install the free Adobe Reader before you can open and view these guides (download Adobe Reader. Be sure to un-check the free McAfee security scan).
The guides are available as separate downloads, so you can grab just the ones you want.
