Use case(s): Fundamental 4: Logical Content Order
Last updated on January 3, 2025
Description
This example demonstrates a failure condition in which the document’s tab order for annotations, such as form fields, links or notes, is not set.
Note: In the sample file, the Tab order is set to “Unspecified.” However, in Acrobat, there is a setting (in the Accessibility preferences) for “Use document structure for tab order when no explicit tab order is specified.” If that checkbox is checked, the sample file may display a correct tab order by chance.
