Question details
The user wants to make specific text or an icon within a PDF clickable so that it triggers explanatory content or a pop-up directly inside the document, without opening an external web page.

- Scenario
- Adding interactive, in-document tooltips, glossary definitions, or explanatory pop-ups to a PDF file.
- Observed behavior
- The user needs a method to show explanations using a link or button action within the PDF, acknowledging that standard hyperlinks do not automatically behave like temporary comment pop-ups.
Ensure you have a fully featured PDF editor installed that supports interactive form fields, buttons, or commenting tools, as basic web-based PDF readers generally cannot create these interactive elements.
Use Button Actions to Show/Hide Explanatory Text
Create a hidden text field and a transparent button that toggles the text's visibility when clicked. This is the most professional way to create custom in-document pop-ups.
By utilizing PDF form controls, you can layer a transparent button over your target text. You then configure this button's action to reveal a hidden text box containing your explanation.
Go to the 'Forms' tab in your PDF editor, add a 'Text Field' where you want the explanation to appear, type your text, and set the field properties to 'Hidden'.
Select the 'Button' tool from the Forms menu and draw a box over the text or icon you want to be clickable. Set the button's appearance to have no border and no fill color.
Right-click the button, select 'Properties', and navigate to the 'Actions' tab. Set the trigger to 'Mouse Up'.
Choose 'Show/hide a field' from the Select Action dropdown, click 'Add', and select your hidden text field. Set it to 'Show' so the explanation appears when the button is clicked.
Use the Sticky Note Comment Tool
If you just need a simple, reliable pop-up explanation without building complex forms, the built-in Sticky Note tool is the fastest method.

Frequently Asked Questions
Can I make the explanation appear by just hovering instead of clicking?
Yes, if you use the form button method, you can set the action trigger to 'Mouse Enter' rather than 'Mouse Up'. This will reveal the hidden text field as soon as the reader's cursor hovers over the button.
Will these clickable PDF explanations work in web browsers?
Simple sticky notes usually work well in browser-based PDF viewers (like Chrome or Edge). However, advanced form field actions (like showing or hiding fields via buttons) often require a dedicated PDF reader such as WPS Office or Adobe Acrobat to function correctly.
How do I make a standard hyperlink act like a pop-up?
Standard hyperlinks in PDFs are designed to jump to different pages or external URLs, not to create pop-ups. To achieve a true pop-up effect without leaving the page, you must use either PDF form buttons with Show/Hide actions or annotation tools like Sticky Notes.
