You add accessibility to your Director movies by using the included accessibility behaviors or special Lingo commands. Director includes several behaviors that let you easily add text-to-speech, captioning, and keyboard navigation to your movies with simple drag-and-drop procedures. These behaviors are located in the Accessibility section of the Library palette.

For keyboard navigation, you use the Accessibility Target, Accessibility Item or Accessibility Text Edit Item, Accessibility Keyboard Controller, and Accessibility Group Order behaviors.

For text-to-speech, you 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, you use the keyboard navigation behaviors and Accessibility Speak behaviors and then add the Accessibility Captioning and Accessibility Synch Caption behaviors.

The source file you downloaded (accessibility.dir) uses 9 of the 10 accessibility behaviors. You can see them in the Cast window.

If you want to have more control over how you implement accessibility in your movies, you can write custom Lingo scripts that use the text-to-speech commands. For more information about text-to-speech Lingo, see Using accessibility Lingo.

The text-to-speech behaviors and Lingo require the Speech Xtra. If you use text-to-speech in your movie, you need to add the Speech Xtra to your movie's Xtra list. The Speech Xtra is discussed in the next section.
