![]() Some re-programmable keyboards that include macro keys allow for the scroll key to be rebound to a custom macro. ![]() Most software, however, ignores the use of the scroll lock key. This allows the users time to read fast scrolling messages that would otherwise be missed. In Linux, pressing the scroll lock key while text is being printed to a console window freezes the output of the console, although the process continues in the background and inputs are still accepted. Other software that still uses scroll lock includes IBM Lotus Notes, Forté Agent, Image-Line FL Studio, Renoise, Microsoft Project, and LibreOffice Calc. For example, Microsoft Excel will change the selected cell if scroll lock is disabled, however, if scroll lock is enabled it will scroll the page in the direction of the arrow key that you press. Not all modern software ignores scroll lock, however, some programs still use for its original intended purpose. Thanks to this, most programs completely ignore the scroll lock key now. On modern computers, this functionality is essentially unnecessary as the mouse allows for much finer control of the cursor and can control scrolling through the use of scroll bars and the scroll wheel. Scroll lock acted as a toggle key, remaining in the same state until it was pressed again, rather than needing to be held down. With scroll lock enabled, however, the arrow keys would scroll the contents of the text window, rather than moving the cursor. By default, with scroll lock off, the arrow keys would move the cursor over the text window. In this time period, there were no graphical interfaces or mice, the computer was entirely text-based and controlled by the keyboard. In which case, open the search menu on your computer and type “On-Screen Keyboard.” Go back to Excel with the keyboard displayed, and hit the Scroll Lock key, “ScrLk,” and this should turn it off.Scroll lock was first included on the original IBM PC keyboard in 1981.
