- Device & OS
- not provided
- Scenario
- Navigating between fillable form fields using the Tab key after enabling document protection.
- Observed behavior
- The Tab key inserts a tab character instead of jumping to the next control, or navigation fails completely due to a mix of legacy fields and modern content controls.
Before troubleshooting, temporarily unprotect your document via the Developer tab to inspect your form fields and identify whether you are using legacy form fields, modern content controls, or a mix of both.
Use Consistent Form Field Technology
Ensure the document uses either entirely legacy form fields or entirely modern content controls, as mixing them breaks Tab navigation.
Combining legacy form fields with modern content controls in the same document creates compatibility issues with Microsoft Word's protection logic. Standardizing on one type of form control will restore seamless Tab key navigation.
Go to the Developer tab, click on 'Restrict Editing', and click the 'Stop Protection' button at the bottom of the side pane.
Review your document to find areas where modern content controls and older legacy form fields are used together.
Delete the mismatched fields and insert the consistent type from the Developer tab so that the entire form relies on a single technology.
Click 'Restrict Editing' again, select 'Filling in forms', and start enforcement to test the Tab key.

Use Group Controls Instead of Legacy Protection
Limit editing by grouping the document rather than using the legacy 'Filling in forms' protection method when utilizing modern content controls.
Use WPS Writer for Seamless Form Creation and Navigation
WPS Writer offers an intuitive interface for inserting form fields and applying document protection, helping you avoid navigation conflicts and formatting issues natively.
- 1. Open the Document: Launch WPS Writer and open your form document.
- 2. Insert Form Fields: Navigate to the Developer tab and insert your desired text form fields uniformly across the document.
- 3. Protect the Form: Click 'Protect Document' in the Review tab and set the restriction to only allow filling in forms.
- 4. Save and Test: Save your document as a .docx file and press the Tab key to smoothly navigate through the active fields.

Frequently Asked Questions
Why does the Tab key insert a tab space instead of jumping to the next form field?
This occurs when your document utilizes a Rich Text Content Control. In rich-text areas, the Tab key acts as a formatting tool to indent text. To fix this, delete the Rich Text control and replace it with a Plain Text Content Control.
Can I mix legacy form fields and modern content controls in the same document?
It is highly recommended not to mix them. Combining both legacy fields and modern content controls within a single document confuses the built-in protection logic, which often breaks Tab key navigation.
How do I remove protection from my Word document to edit the form fields?
Go to the Developer or Review tab, click on 'Restrict Editing', and look at the bottom of the right-side pane. Click the 'Stop Protection' button. If a password was previously set, you will need to enter it.
What is the alternative to locking a document for 'Filling in forms'?
If you are using modern content controls, you can restrict editing by selecting the entire document (Ctrl+A) and choosing 'Group' from the Controls section under the Developer tab. This secures the text around the controls without invoking legacy lock mechanisms.
