Using the Tags tab
The Tags tab allows you to view and edit tags in the logical structure tree, or tags tree, of
a PDF document. In the Tags tab, tags appear in a hierarchical order that indicates the
reading sequence of the document. The first item in this structure is the Tags root. All
other items are tags and are children of the Tags root. Tags use coded element types that
appear in angle brackets (< >); each element, including structural elements such as
sections and articles, appears in the logical structure order by type, followed by a title and
the element's content or a description of the content. Structural elements are typically
listed as container, or parent, tags and include several smaller elements, or child tags,
within them. (For a list of encoded tag types, visit the Adobe website at http://access.
adobe.com.)
Note: For more information on logical structures, expert users can refer to the PDF
Reference, Fifth Edition, on the Adobe website at http://partners.adobe.com/links/acrobat
(English only).
While you can correct most tagging issues by using the TouchUp Reading Order tool in
the document pane (see
Correcting tags ), detailed tagging of tables and substructure
items--such as paragraphs, lists, and sections that require multiple languages--can be
addressed only in the Tags tab. Add tags manually to a document in the Tags tab only as a
last resort; adding tags by using the Adding Tags To Document feature provides greater
detail.
To view tags in the Tags tab:
1. Choose View > Navigation Tabs > Tags, and then drag the Tags tab from the floating
panel to the navigation pane (optional). Or, click the Tags tab in the navigation pane to
display the logical structure tree.
2. Do one of the following:
●
Click the plus sign (+) (Windows) or triangle (Mac OS) next to the tags root and tags to
expand the section you want.
●
Ctrl-click the plus sign (Windows) or Option-click the triangle (Mac OS) next to the Tags
root to show all tags in the logical structure tree.
