The following changes have been made to the SCT.

The SCT chapter of the User Interface book has been restructured into a standalone book. The content has been reorganized and improved using a topic-based approach designed to assist users in finding and applying information to answer a question, solve a problem, or perform a task. Each topic starts with a descriptive heading and includes content that is mostly conceptual, step-by-step procedure, or quick-reference type information. The text is supported by extensive screenshots, and each topic includes a section with links to related topics.

See System Control Table (SCT) for details.
