Keyboard function keys
NOTE:
Keyboard characters may differ depending on the keyboard language configuration. Keys that are used for shortcuts
remain the same across all language configurations.
Some keys on your keyboard have two symbols on them. These keys can be used to type alternate characters or to perform
secondary functions. The symbol that is shown on the lower part of the key refers to the character that is typed out when the
key is pressed. If you press shift and the key, the symbol that is shown on the upper part of the key is typed out. For example, if
you press 2, 2 is typed out; if you press Shift + 2, @ is typed out.
The keys F1-F12 at the top row of the keyboard are function keys for multimedia control, as indicated by the icon on the key.
Press the function key to invoke the task represented by the icon. For example, pressing F1 mutes the audio (see the table
below).
However, if the function keys F1-F12 are needed for specific software applications, multimedia functionality can be disabled by
pressing Fn + Esc. Later, multimedia control can be invoked by pressing fn and the respective function key. For example, mute
audio by pressing fn + F1.
