Using the Order Panel
The Order Panel is a more visual way to edit the tags in a PDF. It's more intuitive to use than the Tags Panel, but has some limitations. Thus, it should be the first step in checking a document after checking the accessibility and/or tagging it with Make Accessible.
The most straightforward process of correcting tags with the Order Panel is to go through the document twice. The first time, you will check the accuracy of the tags present, and in the second, you will check the reading order.
