Can any one say what is the perpous of Fn key. I use sony viao. How the Fn is related to the F1,f2,.....F12 and Numlk key.
The Fn key changes the state of the keyboard so that the next key that is pressed while the Fn key is held down will generate a different scan code than it would without the Fn key. Look at it as an alternate Ctrl or Alt key.
