Testing accessible content

When you test your accessible Flash applications, follow these recommendations:

• If you are designing your document to work with screen readers, download several screen readers and test your application by playing it in a browser with the screen reader enabled. Be sure that the screen reader is not attempting to "talk over" places in your document where you have inserted separate audio. Several screen reader applications provide a demonstration version of the software as a free download and you should try as many as you can to ensure compatibility across screen readers.
• If you are creating interactive content, test it and verify that users can navigate your content effectively using only the keyboard. This can be an especially challenging requirement, because different screen readers work in different ways when processing input from the keyboard—meaning that your Flash content might not receive keystrokes as you intended. Be sure to test all keyboard shortcuts.
