What is a way to identify the reading order of a PDF that has been tagged?

edit

One way to identify the reading order of a tagged PDF is to use a PDF accessibility checker tool, such as Adobe Acrobat Pro or the free tool PAC 2. These tools have a feature that allows users to check the reading order of a PDF and identify any issues with the order. Additionally, users can visually inspect the PDF and look for structural elements such as headings, bold text, and lists, which can give an indication of the reading order. Another option is to consult the document's author or publisher for information about the reading order.
