The keys that are located on a keyboard have different functions. The "Function" key is generally located on the bottom left-hand side of the keyboard with the symbol "Fn." This key is used in combination with other keys to disable, enable or configure specific features. In some cases, the "Function" key will interfere with certain tasks that are performed, so users may need to turn it off. This can be done with a few simple steps.
Steps for Turning off the Function Key
Look on your keyboard for the "Fn" key and hold it down. This is usually located on the bottom left corner of your keyboard, next to the "Alt" key, depending on which model of computer you are using.
Locate the "Num Lock" or "Num Lk" key, whichever way it may appear on your keyboard. Press the "Num Lock" key at the same time as you are pressing the "Fn" key. This should turn off the "Function" key.
Hold down and press the "Fn" + "Shift" + "Num Lk" keys all at the same time to turn off the "Function" key, if the above step didn't work. You may need to use the "Shift" key based on which model of computer you have.
You can press "Fn" + "F1" to make your computer screen go blank if you don't want others to see what you are doing. Press any key to return to the normal screen.
