Question details

- Product
- Adobe Acrobat Reader DC
- Device & OS
- Microsoft Surface tablet / Windows
- Scenario
- Attempting to fill out interactive PDF forms using handwriting-to-text input on a touch device.
- Observed behavior
- The Windows handwriting panel and touch keyboard do not automatically appear when tapping inside a PDF form field.
Make sure your Surface Pen or stylus is paired and functioning properly, and that your tablet is not locked in desktop mode with touch features disabled.
Enable the Windows Taskbar Touch Keyboard Button
By manually displaying the touch keyboard button on your taskbar, you can force the handwriting panel to open whenever you select a PDF form field.
Sometimes, third-party applications like Adobe Acrobat Reader DC do not automatically trigger the Windows touch keyboard. Showing the keyboard button gives you manual control over when the handwriting panel appears.
Right-click anywhere in an empty space on the Windows taskbar at the bottom of your screen, and select 'Show touch keyboard button' from the context menu.
Launch Adobe Acrobat Reader DC and open the PDF document that contains the fillable form fields.
Click or tap inside the specific form field where you want to enter your information.
Tap the newly added keyboard icon in your taskbar system tray, then select the handwriting panel layout to start writing with your stylus.

Frequently Asked Questions
Why isn't my Surface Pen bringing up the handwriting panel automatically in Adobe Acrobat?
Windows sometimes fails to detect when a text field is selected within certain third-party desktop applications. Manually enabling the touch keyboard button on the taskbar guarantees you can access the handwriting panel whenever you need it.
Can I use the handwriting panel to sign a PDF document?
The handwriting panel converts your handwritten input into standard typed text. If you need to insert an actual handwritten signature, you should use the dedicated 'Fill & Sign' or 'Signature' tool within your PDF editing software to draw your signature.
Does the touch keyboard setting stay enabled after restarting my Surface tablet?
Yes, once you enable the 'Show touch keyboard button' setting on your Windows taskbar, the icon will remain accessible in your system tray even after you reboot your device.
