Using the keyboard and mouse
The keyboard and mouse allow you to type, select items, scroll and to perform the same functions as you do by 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 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 the action keys
An action key performs an assigned function. The icon on each of the f1 through f4 keys and f6 through f12 keys illustrates the assigned function for that key.
To use an action key function, press and hold the key.
The action key feature is enabled at the factory. You can disable this feature in Setup Utility (BIOS). See Using Setup Utility (BIOS) and System Diagnostics on page 56 for instructions on opening Setup Utility (BIOS), and then follow the instructions at the bottom of the screen.
To activate the assigned function after you have disabled the action key feature, you must press the fn key in combination with the appropriate action key.
CAUTION: Use extreme care when making changes in Setup Utility. Errors can prevent the computer from operating properly.
