HP 256 G3 Notebook PC - Manual (Page 49)

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 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 the keys
You can quickly access information or perform functions by using certain keys and key combinations.
Using the action keys
An action key performs an assigned function. The icon on each of the f1 through f4 keys, and the f6
through f12 keys illustrates the assigned function for that key.
To use an action key function, press and hold the key.
CAUTION: Use extreme care when making changes in Setup Utility (BIOS). Errors can prevent the
computer from operating properly.
The action key feature is enabled at the factory. You can disable this feature in Setup Utility (BIOS).
See Using Setup Utility (BIOS) and HP PC Hardware Diagnostics (UEFI) on page 58 for
instructions on opening Setup Utility (BIOS), and then follow the instructions at the bottom of the
screen.
After you have disabled the action key feature, you can still perform each function by pressing the
fn
key in combination with the appropriate action key.
