Edit tags with the Reading Order Tool-2

You can use the Reading Order tool to create tags in untagged PDFs or to add new tags to an existing structure. Acrobat analyzes the content of the PDF to interpret the individual page elements, their hierarchical structure, and the intended reading order of each page. Then, it builds a tag tree that reflects that information. It also creates tags for any links, cross-references, and bookmarks that you added to the document in Acrobat.

Note: Add Tags To Document is another tool that can be used to tag an untagged document.  However, it cannot always correctly interpret the structure and reading order of complex page elements. These elements include closely spaced columns, irregular text alignment, nonfillable form fields, and tables that don’t have borders. Tagging these pages by using the Add Tags To Document command can result in improperly combined elements or out-of-sequence tags. These issues cause reading order problems in the PDF.  Before you clear the existing structure, make sure that manual tagging is your only recourse.

 

Add or remove content from a tagged region

 

The Reading Order tool always displays as few highlighted regions as possible. If content within a highlighted region does not flow properly, you may need to split a region to reorder it. Highlighted regions may also contain adjacent page content that is unrelated or that requires a different tag type. Page content may become orphaned from related elements, particularly if the content doesn’t fit within a rectangular shape. Use the Reading Order tool to add or remove content from a region, or to split a region to reorder the content.

  • Select the Reading Order tool.
  • In the Reading Order dialog box, select Show Page Content Groups, and then click Page Content Order.
  • In the document pane, select a highlighted region.
  • Do one of the following:
    • To add content to the current selection, Shift-click the content you want to add. The pointer changes to include a plus sign (+).
    • To remove content from the current selection, Ctrl-click the content you want to remove. The pointer changes to include a minus sign (-).
  • Click the button for the tag type that you want for the highlighted region.
