How to Fix Excel for Mac Keyboard Shortcuts Not Working on Protected Worksheets

Product: Microsoft Excel for Mac
Device & OS: Mac (macOS)
Scenario: Applying cell borders using keyboard shortcuts across multiple worksheets in the same workbook.
Observed behavior: The Option+Command+Arrow shortcut successfully applies borders on some worksheets but has no effect on others, likely due to active worksheet protection.

Before you start

Verify that your Mac keyboard is functioning properly and ensure that the Option and Command keys are registering inputs in other applications.

Solution 1Recommended

Unprotect the Excel Worksheet

Check if the worksheet is locked and remove the protection to restore the functionality of formatting keyboard shortcuts.

Worksheet protection restricts certain actions to prevent accidental changes to the data. If cell formatting is locked by the sheet's creator, styling shortcuts like Option+Command+Arrow will be automatically disabled.

Navigate to the affected sheet

Open your workbook and click the tab of the specific worksheet where the border shortcut is failing.

Open the Review tab

Click on the 'Review' tab located in the top Excel ribbon.

Check for protection

Look for the 'Unprotect Sheet' button. If this button is visible instead of 'Protect Sheet', it confirms the worksheet is locked.

Remove protection

Click 'Unprotect Sheet' to remove the restrictions, then test the Option+Command+Arrow shortcut again to verify borders are applied.

Password Requirement: If a password was set when the sheet was originally protected, you will be prompted to enter it before you can unprotect the sheet.

Solution 2

Adjust Protection Settings to Allow Formatting

If you need to keep the worksheet protected, adjust its specific settings to allow users to format cells.

Yes, you can customize many keyboard shortcuts in Excel for Mac. Go to the 'Tools' menu at the very top of your screen, select 'Customize Keyboard', and assign your preferred key combinations to specific commands.

What does the Option+Command+Arrow shortcut do in Excel for Mac?

In Excel for Mac, the Option+Command+Arrow key combination is traditionally used to quickly apply or remove specific cell borders depending on which directional arrow key is pressed.
