Click the icon 
in the navigation pane to open the Order panel where you can view the reading order. When you click a page in the Order panel, you will be switched to the corresponding page in the document view; when you select a tag in the Order panel, the corresponding content in the document view will be highlighted. In the Order panel, you can also change the reading order of a tagged PDF file without changing the actual appearance of the PDF file if the permission allows. To change the reading order, please do either of the following:
- Select the tag that you want to move and drag it to the desired location. The Line icon
shows the place where the tag will be located as you drag the tag. - Right-click the tag that you want to move and choose Cut from the context menu. Then right-click a destination tag after which you want to move to and choose Paste.
After you drag a tag to a new location, the highlighted regions will be renumbered to show the new reading order.
Tips: In the Order panel, you can use Ctrl-Click to select multiple tags as you click, or Shift-Click to select a listed group of tags between the first and the last tag you click. Then you can move them or right-click them to do more actions.
