Question details
The user is experiencing an issue where typing numbers separated by a space in a PDF text box causes the new numbers to jump to the beginning of the sequence.

- Product
- Adobe Acrobat / PDF Forms
- Device & OS
- not provided
- Scenario
- Filling out or editing a text field within an interactive PDF form.
- Observed behavior
- Entering a sequence like '123456', pressing the spacebar, and typing '789' results in the text displaying as '789 123456' instead of the expected '123456 789'.
Before modifying form properties, ensure that you have editing permissions for the PDF document and are using a PDF editor capable of modifying interactive form fields.
Adjust Text Direction and Alignment Properties
Modifying the text field properties to ensure left-to-right reading order and alignment usually resolves reverse typing issues.
In many cases, the text field may have been accidentally configured with a Right-to-Left reading direction or Right alignment. Reconfiguring these properties will restore normal typing behavior.
Open your PDF editor, activate the 'Prepare Form' or 'Edit Form' tool, and locate the problematic text field.
Right-click the affected text field and select 'Properties' from the context menu to open the configuration dialog box.
Navigate to the 'Options' or 'Appearance' tab within the properties window, and ensure the text alignment is set to 'Left'.
Check for a Right-to-Left text direction setting. If available, toggle this setting back to 'Left-to-Right', then close the properties window and test your input.

Disable Custom Formatting and Scripts
Document-specific JavaScript or custom formatting rules might force numbers to reorder automatically upon keystrokes.

Frequently Asked Questions
Why do my numbers type backwards in some PDF text fields but not others?
This usually happens when a specific text field has its alignment set to Right-to-Left or is configured with a custom number formatting script. Other fields in the same document without these specific settings will behave normally.
Can system keyboard settings affect PDF text direction?
Yes. If your operating system's keyboard layout is switched to a language that reads Right-to-Left (such as Arabic or Hebrew), the PDF editor may automatically reverse the input of numbers and spaces to match the system language.
How do I remove custom formatting from a PDF text box?
You need to enter the form editing mode of your PDF editor. Right-click the text box, select 'Properties', and navigate to the 'Format' tab. Change the formatting category to 'None' to remove any restrictive formatting rules.
Do I need a paid PDF editor to fix text field properties?
While standard free PDF readers only allow you to fill out forms, you generally need an advanced PDF editor with form-editing capabilities (such as WPS PDF Premium or Adobe Acrobat Pro) to alter the underlying field properties and formatting.
