When activated, it prevents any computer function to modify scroll viewing itself at all costs, for example, a computer software can automatically scroll up a page you're viewing, but when this lock is activated, neither the software has the ability to do scrolling itself without your consent.

The scroll lock function on some keyboards can have several different functions. Some of these include placing a break in a document, lock scrolling, and it can toggle between number lock and caps lock.

Back in the days when there weren't any pictures on the computer screen, some programs used that key to allow you to "freeze" the screen for a time so that you had time to read the words.

Where is the scroll lock on dell laptop?

The scroll lock key is located usually on the keyboard, mainly somewhere on the top or lower right.Original Answer: (from wikipedia)The Scroll Lock key was meant to lock all scrolling techniques, and is a remnant from the original IBM PC keyboard, though it is not used by most modern-day software. In the original design, Scroll Lock was intended to modify the behavior 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 usage, Scroll Lock is a toggling lock key like Num Lock or Caps Lock, which have a state that persists after the key is released.
