Hope you are doing well. I believe, you are setting up Text fields under Acrobat>Prepare form tool.
When you open the form in Edit mode. At right hand side toolbar you'll get to see the Fields pane. Fields appear in the order in which they were created.
If this is something related to the form field properties, the right click on the text filed and check the listed properties. You might get the option to change it from there.
thank you for trying to help.
My question is actually targeting another direction: I want to enter text into a PDF document:
In the above image I want to set tab stop points, so text indentation isn't provided by default.
Using Microsoft Word, for example, I'd be using the ruler to set tab stops:
No, you don't have that type of control with text fields.
This is not a text field. You're adding static text. And Acrobat is not a word processing tool, like Word.
Such operations should be done on the original file format, where you would have more control over the formatting than in Acrobat.
