All web documents should be divided into short sections for readability, and should be organized using a clear hierarchy of HTML headings and subheadings (i.e.,

Most screen readers include functionality that allows users to jump between headings with a single keystroke, so blind users can effectively scan the document looking for sections that particularly interest them, just as sighted users typically do.
