Fix F4 and Command+T Reference Toggling Not Working in Excel for Mac
Question details
The user is unable to use the F4 or Command+T keyboard shortcuts to toggle between absolute and relative cell references in Excel for Mac after an update.

- Product
- Microsoft Excel for Mac
- Device & OS
- Mac
- Scenario
- Editing formulas in Excel for Mac version 16.70 or later.
- Observed behavior
- Pressing F4 or Command+T unexpectedly changes the entire reference style of the worksheet instead of toggling the reference type (relative/absolute) for the selected cell.
Check your worksheet to see if the column headers at the top are displaying as numbers (1, 2, 3) instead of the standard letters (A, B, C), as this confirms the R1C1 reference style is active.
Disable the R1C1 Reference Style in Excel Preferences
Turning off the R1C1 reference style will immediately restore the default behavior for the F4 and Command+T shortcuts.
When the R1C1 reference style is enabled in Excel for Mac, it overrides standard formula navigation and reference shortcuts. Disabling this specific setting restores traditional A1-style referencing, allowing your absolute reference shortcuts to work properly again.
Launch Microsoft Excel on your Mac. Click on 'Excel' in the top Apple menu bar and select 'Preferences' from the dropdown.
In the Excel Preferences dialog box, look under the 'Formulas and Lists' section and click on 'Calculation'.
Locate the checkbox labeled 'Use R1C1 reference style' and click to uncheck it.
Close the Preferences window. Select a cell containing a formula and press F4 or Command+T to ensure it now correctly toggles absolute and relative references.

Report the Issue on Office Insider Builds

Frequently Asked Questions
What is the R1C1 reference style in Excel?
The R1C1 reference style is an alternative way of displaying cell coordinates where both rows and columns are numbered (e.g., R1C1 instead of A1). When activated, it fundamentally changes how formulas are structured and can interfere with standard navigation shortcuts like F4.
Why did my column letters change to numbers in Excel?
Your column letters change to numbers when the 'Use R1C1 reference style' setting is inadvertently enabled. You can revert this by navigating to Excel Preferences > Calculation and unchecking the option.
Is there an alternative shortcut to toggle absolute references on a Mac?
Yes, standard absolute and relative reference toggling in Excel for Mac can be done using the Command+T keyboard shortcut, or F4 if your Mac function keys are configured to act as standard function keys. Both shortcuts require the R1C1 style to be disabled to function normally.
