Tagged form fields
In an accessible PDF, all form fields are tagged and are a part of the document structure. In addition, you can use the
tool tip form filed property to provide the user with information or to provide instructions.
To tag form fields, choose Tools > Accessibility > Autotag Form Fields.
Note: See the related WCAG sections: 1.3.1 Info and Relationships. (Level A), 4.1.2 Name, role, value

1 Select one of the Form tools, and then right-click (Windows) or Ctrl-click (Mac OS) the form field.
2 Choose Properties from the context menu.
3 Click the General properties tab.
4 Enter a description of the form field in the Tooltip field.

Alternate text
Figures alternate text
Make sure that images in the document either have alternate text, or are marked as artifacts.
If this rule check fails, do one of the following:
• Select Figures Alternate Text in the Accessibility Checker panel, and choose Fix from the Options menu. Add
alternate text as prompted in the Set Alternate Text dialog box.
• Use the Tags panel to add alternate text for images in the PDF.
• Open the Content panel and right-click (Windows) or Ctrl-click (Mac OS) the content that you want to mark
as an artifact. Then, select Create Artifact from the context menu. (To display the Content panel, choose View >
Show/Hide > Navigation Panes > Content.)
Note: See the related WCAG section: 1.1.1 Non-text Content. (A)
Nested alternate text
Screen readers don't read the alternate text for nested elements. Therefore, don't apply alternate text to nested elements.
To remove alternate text from nested elements, do the following:
1 Choose View > Show/Hide > Navigation Panes > Tags.
2 Right-click (Windows) or Ctrl-click (Mac OS) a nested element in the Tags panel and choose Properties from the
context menu.
3 Remove both the Alternate Text and the text to which it's applied from the Object Properties dialog box, and then
click Close.
