Just look at the keyboard. You can find this button “Scroll Lock”. You can also see the LED “Scroll Lock” near Num Lock and Caps Lock. We have hardly used this. One reason is that there are no software programs that take the advantage of this button.
May be this has become an entertainment. Press Scroll Lock and light comes on. Press again and light goes off.
Scroll Lock is used to temporarily stop the scrolling of text. Microsoft Excel is a good example of a software program that uses this key. If Scroll Lock is enabled on the keyboard , when you press any of the arrow keys, the screen will move in that direction but the selected cell will not change.
Programmers can however make their software respond to the key in whatever way they like, hence it need not be restricted to its original function.
