        The Scroll Lock key is a remnant from the original IBM PC keyboard. In the original design, Scroll Lock was intended to modify the behaviour of the arrow keys. When the scroll lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor. In this sense, Scroll Lock serves a similar purpose to Num Lock, Alt, Shift Key and Caps Lock: it enables a secondary function of a group of keys. Today, this particular use of Scroll Lock is rare. Only a few modern programs still honour this behavior, such as Microsoft Excel (in the behaviour of arrows — when Scroll Lock is on, the selection does not move) and Lotus Notes. In modern GUI environments, scrolling is usually accomplished using other means such as scrollbars or scroll wheels. This is a defunct feature in almost all modern programs and operating systems.

          The scroll lock key is intended to temporarily stop the scrolling of text or halt the operation of a program as per i know.
