Fn key
The Fn key is a special key that is particularly found on notebooks or netbooks . "Fn" stands for "function" or "function" in English. This key can be used to reach a manufacturer-specific level, comparable to the Alt key or control key . The function key has no combinations with the Shift , Alt or Control key .
Usual use
In almost every notebook that does not have a separate number pad , the Fn key switches a block to the function of the number pad. This block is usually located in the right area , similar to normal keyboards , whereby the keys are usually letter keys. Most of the time, the row of function keys also offers the option of controlling the screen brightness, selecting the video output and other things.
The setting whether additional functions can be activated using the Fn key or using the keys F1to F12is made in the BIOS (UEFI) menu.
Position of the Fn key
The position of the Fn key varies depending on the manufacturer and model: usually to the right of the left Ctrl key, or alternatively in the lower left corner of the keyboard.
