The Director Library palette includes an Accessibility section that contains behaviors for enabling keyboard navigation, text-to-speech, and captioning.

• For keyboard navigation, use the Accessibility Target, Accessibility Item or Accessibility Text Edit Item, Accessibility Keyboard Controller, and Accessibility Group Order behaviors.
• For text-to-speech, use the Keyboard Navigation behaviors, and then add either the Accessibility Speak or Accessibility Speak Member Text behavior. You can also use the Accessibility Speak Enable/Disable behavior to let users turn the text-to-speech feature on and off.
• For captioning, use the Keyboard Navigation behaviors and Accessibility Speak behaviors, and then add the Accessibility Captioning and Accessibility Synch Caption behaviors.
