The Option-Command-C keyboard shortcut no longer toggles text capitalization between uppercase, lowercase, and title case in Word for Mac.

How to Fix Option-Command-C Not Changing Case in Word for Mac

Product: Microsoft Word for Mac
Device & OS: macOS
Scenario: A user is attempting to quickly change the text case of selected words using the default keyboard shortcut, but the command fails to execute.
Observed behavior: Pressing Option-Command-C does nothing or triggers a different action instead of changing the case. This is usually caused by recent software updates assigning the shortcut to a different command like Copy Format or new Zoom features.

Before you start

Verify your current versions of macOS and Microsoft Office, as recent Microsoft 365 updates have introduced new shortcuts that may overwrite your custom or default key bindings.
