The Fn key is often combined with the key range from F1 to F12 to toggle various functions based on the system's default settings. You need to explore how to use the Fn key on a laptop keyboard to better understand the usage of this function key.
How to Use the Fn Key on a Laptop Keyboard
1. Toggle Function Key On/Off
Fn Lock functions similarly to Caps Lock. When you activate Fn Lock, you no longer need to press the Fn key separately; just press the key containing that function, similar to how Caps Lock makes letters uppercase.
In the example below, the Fn Lock is the Esc key. To enable Fn Lock, simultaneously press Fn + ESC. To disable Fn Lock, perform a similar action.
2. Adjust Settings in BIOS/UEFI
Most laptop models configure Fn Key settings in the BIOS or UEFI. Therefore, you need to adjust settings in the BIOS/UEFI before using the Fn key on the laptop keyboard. Boot up your computer, use shortcut keys to access Boot Options and BIOS of various computer models, and modify Function Key settings.
3. Modify options in the Control Panel.
If you use Windows through Boot Camp on a Mac, open the Boot Camp Configuration Panel on the System Tray and look for the option 'Use all F1, F2, etc. keys as standard function keys' under the Keyboard tab.
4. Combine shortcut keys with the Fn key.
When simultaneously using the Fn key with one of the shortcut keys below on a Lenovo laptop, you can quickly perform a specific action. Specifically, as follows:
F1 : Mute audio
F3/F2 : Increase/decrease volume
F4 : Close the active window
F5 : Refresh desktop
F6 : Enable/disable Touchpad
F7 : Enable/disable Wifi
F8 : Show all running applications
F9 : Enable/disable the screen
F10 : Output display to external monitor
F12/F11 : Adjust screen brightness
