Some new Office 2013 features are designed to make working with a touchscreen easier. The new Read Mode in Word opens a document in reading view, which lets you scroll through the document by swiping horizontally with your finger. On a desktop with a touchscreen monitor, you can change this behavior back to the more traditional page navigation mode if you wish. Click the Touch Mode button on the Quick Access Toolbar—to the right of the program logo of each application—and the ribbon toolbar spreads its icons further apart for easier access to fingers.
Apart from these useful changes, however, touch integration in Office is somewhat erratic. You can use gestures such as tap, pinch, stretch, slide, and swipe for various features.
