From the adobe website:
"
To use the JAWS screen reader with a Flex application, users must download scripts from the Adobe accessibility website before invoking a Flex application. Screen readers work best when in Forms mode, which lets users interact directly with the Flex application. These scripts let users switch between Virtual Cursor mode and Forms mode by using the Enter key from almost anywhere within a Flex application. If necessary, users can exit Forms mode by using the standard JAWS keystrokes.
Users can download these scripts, and the installation instructions, from the Adobe website at www.adobe.com/go/flex_accessibility."
The link is broken and the marvellously dense chat support person said that Adobe doesn't support Flash Builder.
Where are these scripts located?
