    Hi @Keith Demty,

    Based on your information, there is many factors that can cause the issue happening. Therefore, I suggest you follow this guidance to narrow down the issue step by step:

    1/ Check Scroll Lock

    • Look at the status bar of the bottom left of Excel to check whether you see Scroll Lock there
    • If your keyboard has a ScrLk key, press it once. If not, press Windows + Ctrl + O to open On-Screen Keyboard and click ScrLk there

    2/ Check if the worksheet/workbook is protected

    • Go to Review tab and check if you see the option Unprotect Sheet/Unprotect Workbook
    • If yes, you need to ask for permission to unprotect it since protected sheet usually not allow users without permission to select or make any edit with the data

    3/ Check sticky keys settings

    • Open Settings and go to Accessibility > Keyboard
    • Toggle off Sticky Keys, Filter Keys and Toggle Keys then reopen Excel and test again

    4/ Open Excel safe mode    

    • Press Windows + R to open Run dialog box and type "excel /safe" > press OK to run.
    • If things work normally there, the problem is due to an add-in.
    • Then and go to File > Options > Add-ins > select Excel Add-ins > Go > uncheck all listed add-ins and click OK. Repeat the same steps with the COM add-ins

    • Restart Excel and check if the error is gone. Then re-enable the add-ins one by one and restarting Excel each time to find which one causing the error. 

    5/ Repair Office   

    • Go to Control Panel > Programs > Programs and Features. 
    • Find Microsoft Office, right-click, and choose Change.   
    • Run Quick Repair first. If that doesn’t work, try Online Repair later.

    Tab, Spacebar, and arrow keys are core navigation keys in Excel. When they stop working, the most common causes are keyboard issues or Excel/Office corruption.

    Try these steps in order:

    1. Check for hardware issues
      • Test the same keys in another app (for example, Notepad or Word).
      • If they also fail or work only sometimes, clean the keyboard:
        • Use compressed air to blow under the affected keys.
        • Wipe keys with a slightly damp microfiber cloth.
      • If possible, plug in an external keyboard:
        • If the external keyboard works fine, the original keyboard likely has a hardware problem.
        • If the external keyboard has the same issue, the problem is likely software/driver related.
    2. Verify Excel navigation behavior
      • In Excel, arrow keys normally move one cell up/down/left/right.
      • Tab moves between unlocked cells on a protected sheet.
      • Spacebar and Enter activate selected buttons or open lists when focus is on the ribbon.
      • If these keys work in other apps but not in Excel, continue with repair.
    3. Repair Microsoft 365/Office
      • Close all Office apps (Excel, Word, Outlook, etc.).
      • Open Windows Settings.
      • Go to Apps → Installed apps.
      • Find Microsoft 365 (or Office) in the list.
      • Select the three dots → Modify.
      • Choose Online Repair and confirm.
      • Let the repair complete (can take 15–30 minutes). Do not cancel.
      • Restart the PC after the repair.
      • Open Excel and test Tab, Spacebar, and arrow keys again.

    If the keys still fail only in Excel after an Online Repair and an external keyboard shows the same behavior, further OS/driver troubleshooting is needed beyond this context.
