Scroll Lock is a toggle key that freezes your screen position

Scroll Lock is a keyboard key that stops your mouse wheel or arrow keys from moving down a page. Instead, when Scroll Lock is on, those keys move the entire view up or down while your cursor stays in the same spot on screen. Most people never use it and don't know it exists until it turns on by accident.

The key is usually labeled "Scroll Lock" or "ScrLk" on your keyboard, often near the top right. On laptops, you might need to hold Fn (Function) and press it. When Scroll Lock is active, a small light on your keyboard may glow, or an indicator appears on your screen — depending on your computer.

You've probably hit it without meaning to. It's straightforward to do because the key sits right next to other keys you use all the time. Once it's on, scrolling feels broken: your page won't move the way you expect, and you might think something is wrong with your mouse or trackpad.

Key Takeaways

  • Scroll Lock freezes your position on a page so arrow keys and mouse wheel move the view instead of your cursor.
  • The fastest way to turn it off is to press the Scroll Lock key once — the same key that turned it on.
  • On most laptops, you hold Fn and press Scroll Lock because the key is shared with another function.
  • If your keyboard has no Scroll Lock key, you can turn it off through your operating system settings.
  • Scroll Lock almost never matters in everyday use; it's a leftover feature from older computers.

The quickest fix: press Scroll Lock once

The simplest way to turn off Scroll Lock is to press the Scroll Lock key one time. That's it. The key works as a toggle — press it once to turn it on, press it again to turn it off.

On a desktop keyboard, the Scroll Lock key is usually in the top right area, above the arrow keys. On a laptop, it's often combined with another key. Look for "ScrLk" printed on the key. You'll usually need to hold Fn (the Function key) and then press the Scroll Lock key at the same time.

If you see a light on your keyboard go out, or if an on-screen indicator disappears, Scroll Lock is now off. Try scrolling with your mouse wheel or arrow keys — your page should move normally again.

Finding Scroll Lock on different keyboard types

Desktop keyboards vary by brand, but Scroll Lock is almost always in the top right corner of the main key area, separate from the number pad. On some older keyboards, it sits between Print Screen and Pause. On newer ones, it might be above the arrow keys or integrated into a function key.

Laptop keyboards are trickier because space is tight. Many laptops don't have a dedicated Scroll Lock key at all. If yours doesn't, look for a key that has "ScrLk" printed as a secondary function — often on the same key as another letter or symbol. You'll press Fn plus that key together. On some MacBooks, Scroll Lock doesn't exist as a physical key.

If you can't find the key on your keyboard, the operating system method below will work instead.

Turning off Scroll Lock through Windows settings

If your keyboard has no Scroll Lock key, or if pressing it doesn't work, you can disable Scroll Lock through your computer's settings.

On Windows 10 or 11, open Settings and go to Ease of Access, then Keyboard. Look for "Use Scroll Lock to move through large tables" or a similar option. Turn it off. The exact wording and location can shift between Windows versions, so if you don't see it there, search for "Scroll Lock" in the Settings search bar at the top left.

Some versions of Windows also let you turn Scroll Lock on and off through the On-Screen Keyboard. Press Windows key + U to open Ease of Access, then select On-Screen Keyboard. Look for the ScrLk button and click it to toggle Scroll Lock off.

Turning off Scroll Lock on a Mac

Macs don't have a physical Scroll Lock key, and Scroll Lock as a feature doesn't really exist on macOS the way it does on Windows. If you're using a Mac and your scrolling feels stuck, the problem is usually something else — often a trackpad setting or a stuck modifier key.

If you're using an external Windows keyboard on a Mac, pressing Scroll Lock won't do anything because macOS ignores that key. Check your trackpad settings instead: go to System Preferences, then Trackpad, and make sure scrolling is enabled the way you want it.

Why Scroll Lock exists and when you might actually use it

Scroll Lock is a leftover from the 1980s, when computers had smaller screens and spreadsheets were harder to navigate. The feature let you move around a large table without moving your cursor, which was useful then. Today, almost nobody uses it on purpose.

The only place Scroll Lock still matters is in some spreadsheet programs like Microsoft Excel or Google Sheets, where it can lock your view while you navigate. Even then, most people use the mouse or keyboard shortcuts instead. Unless you work with very large financial spreadsheets all day, you'll probably never need to turn Scroll Lock on intentionally.

Preventing accidental Scroll Lock in the future

The best way to avoid this problem is to be aware of where the Scroll Lock key sits on your keyboard and avoid hitting it by accident. On most keyboards, it's tucked away in a corner, so it's straightforward to miss unless you're reaching for nearby keys in a hurry.

If you find yourself turning Scroll Lock on repeatedly, consider disabling it entirely through your operating system settings. There's no downside to leaving it off — you won't need it for normal computer use, and you'll never have to troubleshoot it again.

Frequently Asked Questions

Why does my page scroll backwards when Scroll Lock is on?

It doesn't scroll backwards — it scrolls the opposite direction from what you expect. When Scroll Lock is on, your arrow keys and mouse wheel move the page view up and down, but your cursor stays in the same spot. It feels backwards because you're used to moving your cursor, not the page.

Can Scroll Lock damage my keyboard or computer?

No. Scroll Lock is just a toggle setting. Turning it on or off does nothing harmful to your hardware or software. It's purely a feature that changes how your input devices behave.

My keyboard has no Scroll Lock key. How do I turn it off?

Use your operating system settings instead. On Windows, search for "Scroll Lock" in Settings and disable it. On Mac, Scroll Lock doesn't exist as a feature, so if scrolling feels wrong, check your trackpad settings or look for a stuck key.

Does Scroll Lock work the same way on all computers?

It works the same on Windows computers, but Macs don't have Scroll Lock at all. If you use an external keyboard on a Mac, the Scroll Lock key won't do anything because macOS doesn't recognize it.

Will turning off Scroll Lock affect any of my programs?

Almost certainly not. The only programs that use Scroll Lock are some spreadsheet applications, and even then, it's optional. You can turn Scroll Lock off permanently without breaking anything.
