scroll lock

I have an acer 9303WSMi and am not sure what the Fn (function key) and F12
do when they are pressed together? It's suppososd to be 'screen lock' but
the websites I visit seem to scroll whichever way they're toggled does it
disable scrolling only in certain programs or is it supposed to stop all
scrolling. TIA

Scroll Lock not Screen Lock - http://en.wikipedia.org/wiki/Scroll_lock

Scroll lock
From Wikipedia, the free encyclopedia

Scroll lock is a key (with an associated status light) on most modern
computer keyboards. The behavior of the key depends on the particular
software in use.

The scroll lock key is a remnant from the original IBM PC keyboard. 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.
Today, this particular use of scroll lock is rare. Only a few modern
programs still honor this behavior, such as Microsoft Excel (in the behavior
of arrows - when scroll lock is on, the selection does not move), Lotus
Notes and Forté Agent. In modern GUI environments, scrolling is usually
accomplished using means such as scrollbars or scroll wheels. Therefore
scroll lock can be regarded as a defunct feature in almost all modern
programs and operating systems; some keyboards lack scroll lock altogether.

Scroll lock has fallen into such extremely infrequent use that some of the
lighter-weight Linux desktop environments don't even support it at all, such
as Xfce.

Also, the scroll lock key is used to switch between the ports on a KVM.
eg. push scroll lock twice then the number of the port.
