Keyboard shortcuts
NOTE: Keyboard characters may differ depending on the keyboard language configuration. Keys 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 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 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 multi-media control, as indicated by the icon at the bottom of the key. Press the function key to invoke the task represented by the icon. For example, pressing F1 mutes the audio (refer to the table below).
However, if the function keys F1-F12 are needed for specific software applications, multi-media functionality can be disabled by pressing fn + Esc. Subsequently, multi-media control can be invoked by pressing fn and the respective function key. For example, mute audio by pressing fn + F1.
NOTE: You can also define the primary behavior of the function keys (F1–F12) by changing Function Key Behavior in the BIOS setup program.
