HP (Hewlett-Packard) C2K79UA#ABA ユーザーズマニュアル

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.

The Windows logo key 

 on the keyboard allows you to quickly return to the Start screen

from an open app or the Desktop. Pressing the Windows logo key again will return you to the
previous screen.

Depending on the country or region, your keyboard may have different keys and keyboard

functions than those discussed in this section.

Your computer has different ways to quickly access information or perform functions with certain keys
and key combinations.

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 

 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.

Use extreme care when making changes in Setup Utility. Errors can prevent the

computer from operating properly.

f1

Opens Help and Support, which provides tutorials, information about the Windows
operating system and your computer, answers to questions, and updates to your
computer.

Help and Support also provides automated troubleshooting tools and access to
support.

f2

f3

Increases the screen brightness incrementally as long as you hold down the key.

f4

Switches the screen image between display devices connected to the system. For
example, if a monitor is connected to the computer, pressing this key alternates the
screen image from the computer display to the monitor display to a simultaneous
display on both the computer and the monitor.

f6
