If an arrow key scrolls the worksheet while the selected cell stays put, turn off Scroll Lock. Press Scroll Lock or ScrLk on your keyboard. If your keyboard has no such key, open the Windows On-Screen Keyboard and click ScrLk there.
01Watch the active cell
Section linkClick a cell in the middle of the worksheet, away from its edges, and press the down arrow. If the sheet scrolls and the active cell address stays the same, check for Scroll Lock on the status bar at the bottom of Excel. If the indicator is missing, right-click the status bar and enable the Scroll Lock indicator so you can check the current state.
02Use the Windows keyboard on screen
Section linkOn Windows 11, go to Settings → Accessibility → Keyboard and turn on On-Screen Keyboard. Find ScrLk on that keyboard and click it to turn Scroll Lock off. Close the On-Screen Keyboard and return to Excel. This works without a physical Scroll Lock key.
03Retest in the worksheet
Section linkClick B2 in a blank sheet and press the down arrow. With normal cell movement, the active cell changes to B3. If the key still behaves differently with Scroll Lock off, test in a new workbook with a cell selected and the cursor outside the formula bar. That comparison separates a worksheet-specific problem from a wider Excel or keyboard issue.
