Use a Simulator to Check Your PDF for Accessibility
This article applies to: Web Accessibility
To make sure that the PDF is sufficiently accessible, use tools to simulate the experience using a screen reader or for a low vision reader.
Simulating the experience of a keyboard reader is also useful. On the tags panel, check to make the order of the tags correct. Then, test the keyboard order by tabbing through the document with your tab key.
