Solution 1Recommended

Reassign the Equation Shortcut and Verify Font

Manually verify and reassign the Insert Equation shortcut in Word options, and ensure the correct font is installed on your system.

Sometimes custom keyboard templates or third-party add-ins can overwrite default shortcuts. Reassigning the shortcut directly in Word's settings usually resolves the conflict.

Open Customize Ribbon Settings

Open Microsoft Word and navigate to File > Options. In the Word Options dialog box, click on Customize Ribbon in the left pane.

Access Keyboard Shortcuts

At the bottom of the window next to 'Keyboard shortcuts:', click on the Customize... button.

Assign the Alt+= Shortcut

In the Categories list, select the 'Insert Tab'. In the Commands list, scroll down and select 'InsertEquation'. Check the 'Current keys' box to see if Alt+= is listed. If it is missing, click inside the 'Press new shortcut key' box, press Alt+= on your keyboard, and click Assign.

Check Cambria Math Font

Close Word and open your computer's Font settings (via Control Panel or Windows Settings). Search for 'Cambria Math' to verify the font is properly installed and enabled on your operating system.

Reassign the Equation Shortcut and Verify Font

Tip: Restart Microsoft Word after making these changes to ensure the new shortcut mapping is applied.
