Hi,
The scroll lock key was meant to lock all scrolling techniques,
though it is no longer used by almost any 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 modifier key like ALT
and SHIFT
(which modify the function of other keys) and, more specifically, a toggling Lock key
like NUM lock
or CAPS lock
, which have a state that persists after the key is released.
