Can Adobe Pro Automatically Bookmark without manual keying?

I have received this to respond to. Is this correct or are tagged bookmarks always manually keyed in?

I am happy to have the bookmarks created from the tagged bookmarks obtained from the document structure. Adobe can identify a documents structure by scanning it, then produce a structured reference e.g., titles, headers etc. This scan then be used to create the bookmarks, this could replace the need to use a manual keystrokes process.

Tagged bookmarks give you greater control over page content than do regular bookmarks. Because tagged bookmarks use the underlying structural information of the document elements (for example, heading levels, paragraphs, table titles), you can use them to edit the document, such as rearranging their corresponding pages in the PDF or deleting pages. If you move or delete a parent tagged bookmark, its children tagged bookmarks are moved or deleted along with it.

Many desktop publishing applications, such as Adobe InDesign® and Microsoft Word, create structured documents. When you convert these documents to PDF, the structure is converted to tags, which support the addition of tagged bookmarks. Converted web pages typically include tagged bookmarks.

If your document doesn’t include tags, you can always add them in Acrobat.
