From the Screen Reformatter

A Wavelink script can be launched for a specific screen using the screen reformatter. When a script is added for a screen in the reformatter, it is considered a screen action. When the correct screen appears on the device, screen actions (including speech‑to‑text and text-to-speech actions) are performed in the order they appear in the Descriptive View. For information on adding a script to a screen using the screen reformatter, see Adding Scripting Support.
