Context-sensitive Help provides information about what users see inside applications — details about fields and controls at dialogs, explanations of messages, and descriptions of windows and screen objects. It is called "context-sensitive" because each topic is called by the application and because it provides information relevant to the task the user is trying to accomplish.
Creating context-sensitive Oracle Help is a collaborative effort between authors and developers. Oracle Help supports context-sensitive Help, but all of the code to make it work properly must be created. Usually, Help authors create context-sensitive Help topics. After the topics are created, developers write the code that enables the context-sensitive Help to work. They also program the Help topics in the application so the correct topics are displayed when users request Help. The developer does this by manually adding the string to the application code so the Help can be invoked. Then the application "calls" the context-sensitive Help using the string.
The Oracle Help equivalent of the .HH file for context-sensitive Help is the map.XML file. This file is generated by RoboHELP when you generate your Oracle Help output. It is located in the directory defined as the output folder when Oracle Help is generated.
