# Reading a PDF with a screen reader

Reader supports assistive software and devices—such as screen readers and screen magnifiers—that enable visually impaired users to interact with computer applications. When assistive software and devices are in use, Reader may add temporary tags to open PDFs to improve their readability. Use the Accessibility Setup Assistant to improve how Reader interacts with the types of assistive software and devices that you use. When using a screen reader, you can change your reading settings for the current document by pressing Shift+Ctrl+5 (Windows) or Shift+Command+5 (Mac OS).

See the documentation for your assistive software or device, or contact the vendor for more information about system requirements, compatibility requirements, and instructions for using this software or device with Reader.
