Most laptop keyboards have a key marked "FN" or "fn". This is just another shift key, like the shift, control, and alt keys. If the instructions say something like "Press fn+F1" then press and hold the fn key, press and release the F1 key, then release the fn key. Exactly the same type of procedure as when the instructions say something like "Press Control+P".

FN (Function Key) that is usually located near the bottom left on the keyboard is not a key that you press by itself to do anything. The FN key works in combination with the (F1 thru F12) and any other key that has the same symbol or color as the FN Key. You have to Press and HOLD the FN key while pressing another key.

If the FN key is Blue and for example your F8 key has a (white F8 on it and a Blue battery icon on it) then to see your battery metor (how much charge it has left) you would Press the FN and hold it then press the F8 key. The F8 that is white does not require you to press the Blue FN.

Sometimes the FN key might have a white square on it, then the keys that work with the FN key will also have a symbol with a white square around it.

The fn key is the function key. I am sure that helps a ton. The fn key works like a shift key, changing the buttons marked fn, like volume, screen brightness, etc. The use is that you press and hold the function key, and press teh function button and then release both.
Common uses are to turn off the mousepad, while typing, and to set screen brightness while under battery....

F1 through F12 are called function keys because they execute programmed functions when pressed. Used in combination with the Fn key, keys marked with icons execute specific functions on the computer. The function executed by individual keys depends on the software you are using.
