The Help API enables opening help catalogs and retrieving help content items such as:
- indexed help topics (XHTML, HTML)
- non-indexed images
- CSS files
- audio/video elements
The API makes it possible to search a help catalog, navigate the table of contents, retrieve keywords, and perform an F1 help topic lookup.
Developers can use this API to create a custom help solution or viewer for a product that uses the new Windows Help Runtime deployed in Windows 8.
