Function Keys
Your LifeBook notebook has 12 function keys, F1 through F12. The functions assigned to these keys differ
for each application. You should refer to your software documentation to find out how these keys are used.
• The [Fn] key provides extended functions for the notebook and is always used in conjunction with
another key.
• [Fn+F3]: Pressing [F3] while holding [Fn] will toggle the Audio Mute on and off.
• [Fn+F4]: Pressing [F4] while holding [Fn] will toggle the Touchpad on and off. Note that the
[Fn+F4] combination only works if Manual Setting is selected in the BIOS. (See “BIOS Setup
Utility” on page 42)
• [Fn+F6]: Pressing [F6] repeatedly while holding [Fn] will lower the brightness of your display.
• [Fn+F7]: Pressing [F7] repeatedly while holding [Fn] will increase the brightness of the display.
• [Fn+F8]: Pressing [F8] repeatedly while holding [Fn] will decrease the volume of your LifeBook
notebook.
• [Fn+F9]: Pressing [F9] repeatedly while holding [Fn] will increase the volume of your LifeBook
notebook.
• [Fn+F10]: Pressing [F10] while holding [Fn] allows you to change your selection of where to send
your display video. Each time you press the combination of keys you will step to the next choice.
The choices, in order, are: built-in display panel only, external monitor only, and both built-in
display panel and external monitor.
