Reading Order. The path taken through a document is called its read-
ing order . Acrobat offers the TouchUp Reading Order tool to define and
order individual content elements on a page.
Select the TouchUp Reading Order tool on the Advanced Edit-
ing toolbar. Alternatively, you can choose Tools > Advanced Editing >
TouchUp Reading Order Tool or Advanced > Accessibility > TouchUp
Reading Order.
Click the PDF page with the tool. The TouchUp Reading Order dia-
log opens, and the content of the page is shown in separate gray num-
bered blocks. The numbers identify the document’s reading sequence
(Figure 49b). Read some tips for using the tool and touchup process in
the sidebar “Order Up Reading Order.”
