Use the Keyboard Shortcut for Manual Line Break

Using the Shift+Enter shortcut is the quickest and most reliable workaround when the ribbon command for a manual break becomes unresponsive.

In Microsoft Word, using the standard Enter key often breaks the equation block into two separate paragraphs. A soft return keeps the lines together in the same mathematical container, preserving your alignment settings.

1
Position the cursor

Click exactly where you want the line break to occur inside your active equation box.

2
Use the shortcut

Press the Shift and Enter keys on your keyboard simultaneously.

3
Verify the break

Check if a new equation line starts on the next text line while remaining inside the same equation boundary.

Frequently Asked Questions

Why did the equation editor break in Word 2016?

Microsoft Word 2016 utilizes a newer built-in equation editor instead of the legacy Microsoft Equation 3.0. Compatibility issues with older documents, missing software updates, or corrupted formatting can occasionally cause ribbon commands like Insert Manual Break to fail.

How do I align multiple lines in a Word equation?

After inserting a manual break using Shift+Enter, type an ampersand (&) directly before the character you want to align on each line (such as the equals sign). Then, right-click anywhere in the equation and select 'Align at this character'.

Can I use the Enter key instead of Shift+Enter for equations?

Pressing Enter alone typically creates a hard paragraph break, which splits the equation into two entirely separate blocks and ruins your ability to align them together. Shift+Enter creates a soft break, keeping both lines securely within the same equation container.

Does WPS Office support editing Microsoft Word equations?

Yes, WPS Office fully supports reading, editing, and formatting equations created in Microsoft Word. You can easily insert manual breaks, modify fractions, and align mathematical symbols without losing your original document layout.
