What is Scroll lock?
'''Scroll lock''' (or ScrLk) is the name of a key on a [[computer keyboard]] that was meant to lock all scrolling methods. The scroll lock key is rarely used and only came about because the original [[IBM]] [[PC]] keyboard had it. It was supposed to change how the [[arrow keys]] work. For example, when the scroll lock mode was turned on, the arrow keys would scroll the contents of a text [[Window (computing)|window]] instead of moving the [[cursor]]. Today, the key doesn't do anything in most [[Computer program|programs]], and as a result, many keyboards today, especially those on [[laptop]]s and mobile devices, do not have the scroll lock key. {{Tech-stub}} [[Category:Computer keyboard]]
