soſtware and devices, such as saving as accessible text for a Braille printer
•
Preferences and commands to make navigation of PDFs more accessible,
such as automatic scrolling and opening PDFs to the last page read
•
An Accessibility Setup Assistant Wizard for easy se±ing of most
preferences related to accessibility
•
Keyboard alternatives to mouse actions
•
Reflow capability to temporarily present the text of a PDF in a single,
easy-to-read column
•
Read Out Loud text-to-speech conversion
•
Support for screen readers and screen magnifiers
•
Support for high contrast and alternative foreground and background
colors
Features to Support the Creation of Accessible PDFs
•
Creation of tagged PDFs from authoring applications
•
Conversion of untagged PDFs to tagged PDFs from within Acrobat
•
Security se±ings that allow screen readers to access text while preventing
users from copying, printing, editing and extracting text
