Using the keyboard
The keyboard and mouse allow you to type select items, scroll and to perform the same functions as using touch gestures. The keyboard also allows you to use action keys and hot keys to perform specific functions.
TIP: The Windows key 
on the keyboard allows you to quickly return to the Start screen from an open app or the Windows desktop. Pressing the Windows key again will return you to the previous screen.
NOTE: Depending on the country or region, your keyboard may have different keys and keyboard functions than those discussed in this section.
Using Windows shortcut keys
Windows provides shortcuts so that you can perform actions quickly. Press the Windows key 
alone or in combination with a specific key to perform a designated action.
