I just thought I'd post this since I began digging through my collection of
materials related to JAWS (and other screen readers) and Adobe Reader.
Here is the Accessibility Page for Adobe Acrobat DC. I imagine the two links
with the titles, Acrobat DC accessibility features and Acrobat DC accessibility
FAQ will be of the most interest to end users. They put together a reasonably
useful document entitled, Accessing PDF documents with assistive technology: A
screen reader user’s guide, as well.
