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.

1
Place the text box

Select the Add Text Comment tool and click anywhere on the document page to place the box.

2
Trigger the properties menu

Double-click inside the comment box and begin typing your text to trigger the Text Properties (Aa) controls.

3
Select the text

Highlight the text you just entered. The formatting options will only apply to the selected characters.

4
Change font and size

Adjust the font type and text size using the newly appeared formatting toolbar.

Frequently Asked Questions

Why is my text formatting toolbar missing when I add a comment?

The formatting toolbar usually remains hidden until you double-click inside the text box and actively begin typing, or until you highlight existing text inside the box.

Can I set a default font and size for all future text comments?

Yes. Once you format a text comment to your liking, right-click the text box, select 'Properties', and check the option labeled 'Make Current Properties Default'.

Will comments formatted in WPS PDF display correctly in other PDF viewers?

Absolutely. WPS PDF uses standard PDF annotation protocols, ensuring your font and size changes are fully visible and compatible across all standard PDF readers.
