Define the tabbing order

In the Pages panel, you can set the order in which a user tabs through form fields, links, and comments for each page.

Click the Pages button on the left.
Select a page thumbnail, and choose Page Properties from the Options menu.

In the Page Properties dialog box, click Tab Order, and select the tab order:

Option	Description
Use Row Order	Moves through rows from left to right, or right to left for pages with a right-to-left binding.
Use Column Order	Moves through columns from left to right and from top to bottom, or right to left for pages with a right-to-left binding.
Use Document Structure	Moves in the order specified by the authoring application. Note: For structured documents—PDFs that were created from desktop publishing applications or that contain tags—it’s best to select the Use Document Structure option to match the intention of the authoring application. If the document was created in an earlier version of Acrobat, the tab order is Unspecified by default. With this setting, form fields are tabbed through first, followed by links and then comments ordered by row.
