On most modern Logitech keyboards, the Logitech keyboard scroll lock function is not on a dedicated key; instead, it's a secondary action hidden on another key, usually labeled with a small "Scr Lk" text or a symbol of a box with a downward arrow. If you don't see that label anywhere on the top row, look for the Fn key near the bottom-left corner, you'll need to hold it and press the key bearing the Scroll Lock symbol to toggle the feature.
Where is the Logitech keyboard scroll lock key?
For the majority of current Logitech models, especially compact, wireless, and tenkeyless (TKL) designs, the Scroll Lock key is not physically present. Instead, Logitech places the Scroll Lock function as a secondary command on another key, typically in the top row of function keys. The visual cue to look for is either the text "Scr Lk" printed in a contrasting color or a small icon that resembles a rectangle with a downward-pointing arrow. If your keyboard has backlighting, the secondary function labels are often illuminated when the Fn key is active, making them easier to spot.
When you find the key with the Scroll Lock symbol, the action is simple: press and hold the Fn key (usually located in the bottom row, to the left of the Windows key) and then tap the key with the "Scr Lk" label. This toggles Scroll Lock on and off.
How to use Fn key combinations for Scroll Lock
The most common method across Logitech's lineup is the Fn-key combination. Here's the step-by-step process that works for the vast majority of compatible models:
- Locate the Fn key on your keyboard, it's almost always in the bottom-left corner, next to the Ctrl key.
- Find the key that carries the Scroll Lock symbol (a box with a downward arrow) or the "Scr Lk" text.
- Press and hold the Fn key, then press the Scroll Lock key once.
- Release both keys. If your keyboard has a Scroll Lock indicator light, it should now be lit (or unlit, if you were turning it off).
For specific Logitech models like the G413 TKL SE and the MK850, the exact combination is Fn + Home. This is a deliberate design choice, these keyboards omit the dedicated Scroll Lock key entirely, so Logitech assigns the function to the Home key in the navigation cluster. If you own one of these models, simply hold Fn and tap Home to toggle Scroll Lock. If you're unsure whether your model uses this combination, check the bottom of the Home key for a small printed symbol; if you see a box with a downward arrow, that's your Scroll Lock trigger.
What to do if your keyboard has no Scroll Lock function
If your Logitech keyboard doesn't have a physical Scroll Lock key and you can't find any Fn combination that works (some ultra-compact models omit the function entirely), the definitive fallback is the Windows On-Screen Keyboard. This built-in tool works with any keyboard, regardless of model, and gives you a virtual "ScrLk" button that you can click with your mouse. This is the most reliable method when your hardware simply doesn't support the function.
To use it, press the Windows key, type "osk" (without quotes) into the search box, and press Enter. The On-Screen Keyboard will appear on your screen, it's a full virtual keyboard that mirrors a standard layout. Look for the "ScrLk" key on the right side of the virtual keyboard, usually in the same position as on a full-size physical keyboard. Click it once to toggle Scroll Lock. The On-Screen Keyboard stays open until you close it, so you can click the button again later to turn Scroll Lock off.
Customizing keys with Logi Options+
For compatible Logitech keyboards and mice, the Logi Options+ software offers a more permanent solution: you can reassign any key to perform the Scroll Lock function. This is particularly useful if you use Scroll Lock frequently in Excel or other spreadsheet applications and want a dedicated, always-available key. After installing Logi Options+ from the Logitech website, open the app, select your keyboard from the device list, and choose the key you want to remap. In the assignment menu, search for "Scroll Lock" under the "Keys" or "Function" category, then save your profile. The reassignment takes effect immediately, and you'll have a one-press Scroll Lock toggle on a key that previously did something else. Note that this feature is only available on devices that support Logi Options+; older or budget models may not be compatible, in which case the On-Screen Keyboard method above is your best bet.
Why Scroll Lock still matters in Excel
Scroll Lock's primary modern use case is in Microsoft Excel, where it changes how the arrow keys behave. When Scroll Lock is on, pressing the arrow keys scrolls the entire worksheet, moving the view up, down, left, or right, while the active cell stays exactly where it is. When Scroll Lock is off, the arrow keys move the cell selection instead. This is critical for anyone who needs to compare distant parts of a large spreadsheet without losing their place: you can scroll to see other data while keeping your active cell highlighted for reference. To check whether Scroll Lock is currently active in Excel, look at the status bar at the bottom of the window, if it says "Scroll Lock" (or just "SCRL") on the right side, the feature is on. Clicking that status bar text also toggles Scroll Lock, providing yet another way to control it without touching your keyboard. If you've ever pressed an arrow key in Excel and the whole sheet moved instead of the cell cursor, you now know exactly what caused it, and how to fix it using any of the methods above.
