Fn, or 'Function,' is a modifier key on manykeyboards, especially on laptops, used in a compactlayout to combine keys which are usually kept separate. It is typically found on laptops, since a full sized keyboard would be difficult to fit in a laptop chassis. It is also found in many full-sized 'multimedia' and 'office' keyboards, named F Lock key. It is mainly for the purpose of changing display or audio settings quickly, such as brightness, contrast, or volume, and is held down in conjunction with the appropriate key to change the settings.
The Fn button is the function key. A key that works like a shift key to activate the second function on a dual-purpose key.
The FN key is reliable for all F key needs. However, if the FN key is selected twice it will separate primary function from dual function.
scroll lock + fn key
The "Fn" key is a modifier key, much like "Shift." By itself, it does nothing. Its purpose is to use an alternative function, such as volume control or to switch to another monitor, that has been mapped to a key on the keyboard. Holding the Fn key and one of the other designated keys activates the function.
All Macs should have a fn key in the very bottom left corner. It is under the Shift key and next to the control key.

If you are using mac, and the f5 key does not work, it is because you are not holding down the fn key. The fn key should be on the bottom left side of your keyboard. Hold down the fn key while pressing f5 and it should work. Hope this helps!

Press the num lock key but if it is on f11 or something hold the fn key and press it
Pres the "FN" key while hitting the NumLock (Num) key one OR MORE times, depending on the sign on the "Status indicator panel" (E-Series). When the Num Lock indicator has vanished, the FN key is deactivated.
