Editing Scroll Lock (section)

===Other uses===
[[IBM PC]] documentation called {{keypress|Scroll Lock}} an "inactive key". When ''[[PC Magazine]]'' asked an executive of keyboard manufacturer [[Key Tronic]] about the key's purpose in a 1983 interview, he replied "I don't know, but we put it on ours, too."<ref name="sandler198301"/>

The indicator light is sometimes used for other purposes such as a [[keyboard layout]] indicator<ref name="Ubuntu"/><ref name="Gnome"/> in some [[Linux distributions]] or other applications,<ref name="Keyboard_illuminator"/> because doing so is less likely to cause problems than manipulating other keys/lights.

[[KVM switch|Keyboard, video, mouse switches]] (KVM) often use the Scroll Lock key on the keyboard connected to the KVM switch for selecting between computers. On KVM switches with [[On-screen display]] (OSD), a "double click" of the Scroll Lock key often brings up the OSD, allowing the user to select the desired computer from a list or access the configuration menu of the KVM. Some models, especially those without an OSD, switch to the input corresponding to the number key pressed after Scroll Lock, or in the case of some two-port switches, the up and down arrow keys. Simple models with only two or four inputs may immediately switch to the next input following a double press of the Scroll Lock key.

This section, restored from the article's previous edit history, needs more clean-up before it can be reenabled into the live article. I put it back in here so that the information is easier accessible and does not get lost easily:

* In [[FL Studio]], the Scroll Lock key, when on, will prevent the screen from scrolling when the time marker moves out of the visible area.
* On some [[Dell]] [[laptop]]s the Scroll Lock key becomes the [[Fn key]] when an external keyboard is used. This behavior can be disabled in the [[BIOS]].
* In most 'LED light' Mods for keyboards, to give the keyboard an overhead LED so the keyboard can be lit up, the Scroll lock key is used to switch it On and Off and the LED light is unsoldered and a new brighter LED is attached overhead the keyboard.
* In the [[Opera (web browser)|Opera]] [[web browser]] the Scroll Lock key is utilized to toggle "listening mode" for the browser's built-in [[Speaker recognition|voice recognition]] feature.
* In [[Synergy (software)|Synergy]], the Scroll Lock key is utilized to lock the use of mouse and keyboard functions to a specific PC.
* In [[Stepmania]], pressing the Scroll Lock key opens the Options menu.
* In the multilingual text editor [[iLeap]], the Scroll Lock key is used as a toggle switch to change between two languages.
* [[X Window System]] can be configured to indicate changing to an alternative keyboard layout by turning on the Scroll Lock light.
* In [[FreeBSD]], and other [[Berkeley Software Distribution|BSD]] descendants, Scroll Lock still functions similarly to [[IBM]]'s original design.
* Individual applications may assign any function to this key as an added convenience [[keyboard shortcut|hotkey]].
* [[Xfire]], a chat application for use while playing a video game, is activated by using the default key combination of "Scroll Lock" + "X". Xfire also uses Scroll Lock for other in-game purposes, such as taking screenshots. Sometimes its [[Light-emitting diode|LED]] is used to notify users that an event occurred.
* In the media system [[My media system|My Media System]], navigation is done in a fashion very similar to the original idea of the Scroll Lock key. At the beginning and end of a list, navigating will move the cursor but not the view. In the middle of the list, the cursor will be locked in the middle of the screen while the view moves.
* [[Konsole]], a [[terminal emulator]] for [[KDE]] uses the Scroll Lock key to make the arrow keys scroll back the buffer, rather than going up and down in the command history (the default behavior of the arrow keys in Konsole). This has often led to problems while using the [[Xine]] media player, as Xine emits a Scroll Lock key signal to prevent the screensaver from starting. This will in turn make Konsole switch the arrow key behavior. {{Citation needed|date=November 2008}}
* [[Maplestory]], an online [[MMORPG]], utilizes the Scroll Lock key to take pictures, ignoring its toggling function (that is, it does not matter if the Scroll Lock LED is on or off).
* [[Combat Arms (video game)|Combat Arms]], a [[free-to-play]] [[microtransaction]]-based [[first-person shooter]], uses the Scroll Lock key to lock the movement of chat messages.
* [[TeamViewer]], a program that allows users to watch and control another person's screen for use of technical support, uses the Scroll Lock key when viewing to send hotkeys directly to the person being viewed/controlled instead of the viewer's computer. For example, if the user wants to open task manager using CTRL+ALT+DEL on the computer or another user at that time, the scroll lock should be turned on.
* Many programs (e.g. e-mail clients) will toggle the Scroll Lock and in the process flash the [[LED]] on and off to alert the user's attention.
* [[Winamp]] uses scroll lock in its main visualizer, [[MilkDrop]]. When pressed, the visualizer preset is then locked and will not change until the scroll lock is pressed again.
* The N64 Virtual Pad controller plugin for [[Project64]] and [[1964 (emulator)]] was the first to emulate the [[Nintendo 64 Rumble Pack]], which it does so by flashing the Scroll Lock LED.
