Editing Forms Accessibility in Adobe Acrobat (section)

== Form field tab order ==

Form field tab order must match the flow of the document: left to right, then top to bottom, with the exception of columns where it makes more sense to go from the top to the bottom of the leftmost column, then return to the top of the next column to the right. 

* '''Tools pane''' > '''Forms''' > '''Edit''' > '''Fields tab'''
** Drag form fields to the appropriate place in the list.
** '''''Note''' that changing the position of a field in the list will remove its tag from from the tags tree. After a field's tab position is changed, re-tag it with '''tags''' pane > '''options''' menu > '''Find...'''. (See [[#Form_fields_must_be_represented_by_tagged_annotations_in_the_tags_tree|Untagged annotations]])''
* Document tab order
** When the Accessibility Check is run after the field tab order has been changed, an error will be thrown under '''Accessibility Checker''' > '''Page Content''' > '''Tab Order'''
** Expand the node, right click on the error message and select '''Fix'''.
