To create context-sensitive Help, you need to add markers in your documentation that the product developers can link to from the corresponding parts of the product. The CSH (context-sensitive help) Marker feature in FrameMaker allows you to apply TopicAlias markers in your documentation. The CSH markers are then used by the publisher to add anchors in the publish output. The publisher also creates a map file that the product developers use to link to the anchors in the documentation.
Context-sensitive Help markers are used in the following publish output formats:
