Hot key combinations

Keyboard shortcuts

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: Keyboard characters may differ depending on the keyboard language configuration. Keys used for shortcuts

remain the same across all language configurations.
