Dealing with non-responsive arrow keys in Excel can be highly frustrating, especially if it hampers your productivity. When the arrow keys on your keyboard stop working while you’re managing spreadsheets in Excel on a Windows system, there are several potential solutions that you can try to resolve the issue.

Firstly, ensure that the problem is, in fact, with Excel and not your keyboard. Tap the arrow keys within another program or a text document. If they work elsewhere, you can rule out hardware issues and concentrate your troubleshooting efforts on Excel.

One common reason for arrow keys not functioning in Excel is that Scroll Lock is enabled. The Scroll Lock key changes the behavior of the arrow keys and is typically located at the top right of most keyboards, labeled as “Scroll Lock” or “ScrLk”. Press this key once to disable it, and your arrow keys should start working immediately in Excel.

If pressing the Scroll Lock key doesn’t resolve the issue, checking Excel’s settings is the next step. Occasionally, Excel’s Sticky Keys feature might be turned on inadvertently, which could prevent the arrow keys from functioning correctly. To turn off Sticky Keys, press the “Shift” key five times rapidly or go to Control Panel > Ease of Access Center> Make the keyboard easier to use and uncheck “Turn on Sticky Keys.”

Alternatively, if only one or two arrow keys are not working, it could mean there are issues with specific cells or formulas. In such cases, evaluate those cells to ensure they’re not part of a larger array formula or are merged with others which might restrict movement around them.

Another troubleshooting tip involves resetting keyboard shortcuts within Excel. Sometimes personalized shortcuts overwrite default settings that control navigation. Resetting these by going to File > Options > Customize Ribbon > Keyboard Shortcuts will restore arrow key functionality if they were affected by customized shortcuts.

Lastly, if all else fails, a complete repair of Microsoft Office might be necessary to fix deeper issues. This can be done through Control Panel > Programs and Features. Right-click on Microsoft Office and select “Change” then choose “Repair.”

If none of these solutions work for you, it may be time to consult with IT support or consider reinstalling Excel entirely.

By methodically checking each of these possible solutions – from ensuring Scroll Lock is off to repairing Microsoft Office – you can usually diagnose and rectify any issues preventing your arrow keys from operating correctly in Excel under Windows systems.
