How to Fix Cannot Type Text in Adobe Acrobat Comment Box
Question details
The user is unable to input text into the comment box in a PDF document after selecting the Comment option from the context menu.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Adding annotations and text comments to a PDF document.
- Observed behavior
- Text can be added successfully after highlighting or striking through, but the comment box accessed via the standard right-click context menu does not register keyboard input.
Ensure your Adobe Acrobat software is updated to the latest version and verify that the PDF document's security settings permit commenting.
Use a Dedicated Commenting Tool Before Typing
Activating a specific commenting tool from the toolbar instead of relying on the right-click menu often resolves input glitches.
Sometimes Acrobat fails to recognize the selected object as a valid comment container when bridging from the context menu. Forcing the software to use a dedicated tool initializes the comment properties correctly.
Open your PDF document in Adobe Acrobat, navigate to the Tools menu at the top of the interface, and select Comment to reveal the commenting toolbar.
Click on a specific tool on the ribbon, such as the Add text comment (the T icon) or the Sticky Note tool.
Click on the exact area of the PDF page where you want to leave your comment and try typing your text. The box should now accept input.

Verify Document Security Settings
Check if the PDF file has inherent security restrictions that are preventing standard commenting actions.
Add PDF Comments Easily with WPS Office
If your current PDF software frequently struggles with input bugs or unresponsive comment boxes, switching to WPS Office is a perfect solution. The built-in WPS PDF tool offers a smooth, lightweight way to add notes, text boxes, and highlights without interruptions.
- 1. Open your PDF: Launch WPS Office and open your target PDF document.
- 2. Access Comment Tools: Navigate to the Comment tab located on the top ribbon of the WPS PDF interface.
- 3. Add Your Text: Select Text Comment or Note, click anywhere on your document page, and begin typing instantly without errors.

Frequently Asked Questions
Why is my PDF comment box grayed out or unclickable?
The comment box may be grayed out if the PDF has security restrictions, if it is opened in restricted mode, or if you are using a basic default viewer (like a browser viewer) instead of dedicated PDF software.
Can I edit existing comments in Adobe Acrobat?
Yes, you can edit existing comments by double-clicking the comment icon on the page or by selecting the text within the right-side Comments pane, provided the document commenting privileges are not locked.
Do annotations from WPS PDF show up correctly in other PDF readers?
Yes, comments, sticky notes, and text annotations added in WPS PDF adhere to standard PDF formatting rules and will remain fully visible when the file is opened in Adobe Acrobat or other third-party PDF readers.
