Each item in a form can have an accessibility-specific message associated with it. When a screen reader is active, the Viewer checks items for these messages as each item receives the focus. The Viewer then passes the message to the screen reader, which reads the message aloud for the user, along with some general information about the item.
If a form does not have any accessibility-specific messages, the screen reader still reads general information about each item, but this information may not be clear to the user.
The Viewer automatically activates screen reader support when an MSAA-compliant screen reader is running.
If you are using a release of JAWS 5.0 prior to build 813, JAWS will not work properly when the Viewer is embedded in a browser. To correct this problem, we recommend upgrading to a later version of JAWS.
