- Device & OS
- not provided
- Scenario
- Adding text comments or annotations to review a PDF document.
- Observed behavior
- The font and size controls for the Add Text Comment tool do not respond or fail to appear when trying to format the text.
Ensure you have clicked inside the text comment box and actually selected the text you want to format, as properties cannot be applied to an empty or unselected text box.
Activate Text Properties by Editing the Comment
Use this method to reveal the hidden text properties toolbar by actively typing and selecting text inside the comment box.
In many PDF editors, the formatting toolbar is contextual. This means it remains hidden to save screen space until you are actively editing the contents of a text box.
Select the Add Text Comment tool and click anywhere on the document page to place the box.
Double-click inside the comment box and begin typing your text to trigger the Text Properties (Aa) controls.
Highlight the text you just entered. The formatting options will only apply to the selected characters.
Adjust the font type and text size using the newly appeared formatting toolbar.

Adjust Appearance via the Right-Click Properties Menu
Access the default properties dialog to change general appearance settings if the quick contextual toolbar fails to appear.
