Okay, look for a button that says "Fn lock" It will most likely be printed off-color (like all the other Fn keys) This works just like capslock does for capital letters. Pressing Fn & Fn-lock simultaneously should unlock the Fn mode. Another way with laptop key boards is to press the numberlock key . This seems to switch off nos. appearing for letters
scroll lock + fn key
its because your keyboard has "456" there as well as the letters and the numbers are activated when using the fn 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.
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.
One reason the Fn key may appear stuck is if you recently plugged a full-size keyboard into your laptop and pressed the NumLock key. This key activates the Fn key on the laptop. To return the Fn key to its original state, plug in the keyboard and disengage the NumLock key. Remove the keyboard and test out any of the Fn assigned keys. They should return to normal working status. If it doesn't however, you may require further troubleshooting. You can find out if its the numlock by holding the fn key to type normally. if it types normally then and oposite when released then that's the problem. you can turn it off by holding the fn key and presing either the blue "num <arrow down>" or the blue numlock key. (both are numlock just look different on some laptops.
Fn - especially calculator or laptop is the key that accesses the other functions of certain keys depending upon keyboard manufactry i.e. holding down the Fn key whilst using the F2, F3 etc keys will, on sony laptop adjust volume - written in blue as is the Fn key, holding down the shift +Fn key will give you the function of the other coloured keys.

It's used to activate a search or put the computer to 'sleep'. Pressing F3 on its own drops down a small window where you can type a word (or words) to search for. Once you enter the search string - successive presses of the F3 key will jump to the next occurrence. Pressing the Fn key + F3 together puts the computer into sleep mode.
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.
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!
