The user is experiencing issues with backspace and arrow key navigation within Microsoft Word form fields.

Fix Backspace and Navigation Problems in Word Form Fields

Product: Microsoft Word
Device & OS: not provided
Scenario: Filling out or editing an older Microsoft Word form.
Observed behavior: The backspace key removes only one character and then stops working. Arrow keys cannot navigate backward between fields. Recreating the form and removing updates did not resolve the issue.

Before you start

Before troubleshooting, ensure you know your current Windows and Office version (found under File > Account in Word) and make a copy of your document to prevent any accidental data loss.

Solution 1Recommended

Check and Standardize Form Control Types

Ensure you are not mixing legacy form fields and modern Content Controls in the same document, as this commonly causes keyboard navigation glitches.

Microsoft Word supports different generations of form controls. Mixing Content Controls and Legacy Form Fields in the same form often restricts proper keyboard navigation, leading to backspace and arrow key failures.

Enable Developer Tab

Open the problematic Word document. If the Developer tab is not visible, go to File > Options > Customize Ribbon and check the Developer box.

Inspect Form Fields

Go to the Developer tab and click Design Mode to inspect the form fields in your document.

Identify Control Types

Check whether the fields are Legacy Tools (gray shaded boxes) or Content Controls (boxes with bounding titles).

Unify the Form Controls

Replace the mixed fields so the entire document uses only one type of control, preferably modern Content Controls, to restore normal backspace functionality.

Check and Standardize Form Control Types

Avoid Control Mixing: Always stick to either Content Controls or Legacy fields entirely within a single document. Mixing them is the most common cause of form navigation bugs.

Solution 2

Run Word in Safe Mode

Start Word in Safe Mode to determine if an add-in or startup file is interfering with your keyboard inputs.

Solution 3

Repair Office and Reset Word Settings

If the issue persists, repairing your Office installation or resetting Word's global template and registry settings can fix deep-rooted application errors.

Frequently Asked Questions

Why does the backspace key stop working after one character in Word forms?

This typically happens when a document mixes Legacy Form Fields with modern Content Controls. Word's document protection and navigation engine struggles to handle both simultaneously, causing keyboard inputs like backspace and arrow keys to lock up.

How can I check my Office version to help troubleshoot this issue?

Open Microsoft Word, click on 'File' in the top-left corner, and select 'Account' from the menu. Your Office version and build number will be clearly displayed under the Product Information section on the right side.

What is Normal.dotm and why should I back it up before resetting Word?

Normal.dotm is the global default template file that dictates the basic formatting, styles, and macros for all new Word documents. Backing it up (or simply renaming it) allows you to restore your personalized settings if resetting it doesn't fix your form field navigation problem.
