Microsoft Office is finally available for iOS, but prepare for disappointment. It's only for the iPhone, and the app requires an Office 365 subscription, which starts at $60 a year. In addition to those limitations, the apps are bare bones, lacking many seemingly basic features: you can't undo actions or change fonts in Word, nor can you add slides or create new documents in PowerPoint. follow link
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
