Lists provide a simple way to group related items together so they are easy to read. If the list items are coded as paragraph text, then the text will read as if it is one paragraph or a disjointed run-on sentence . If coded properly , assistive technology can let users know when they are entering and exiting a list and how many items to expect in that list . Update the Tags Pane to allow lists to be part of the document structure.
