Sometimes, you might feel the need to create help files relative to the action performed by the user. Such help is called Context-Sensitive Help (CSH). For example, you can provide help information when a user hovers over a dialog box or other objects. The process of creating a CSH involves specifying map IDs and map files. The help engine receives the map number and help file name whenever the user accesses a CSH. The Help engine then matches the map number to a topic ID and HTM file and displays the correct help topic.
RoboHelp supports three types of CSH −
Window-level − This level of CSH provides topics for windows, dialog boxes and other fields. Users can access window-level CSH by calling the Help function within the application or pressing F1.
Field-level (What's This?) − This CSH describes information when a user clicks on a question mark icon and then clicks a field or function. “What’s This?” topics are supported only by WinHelp and MS HTML Help projects.
Airplane Help − This usually refers to offline help that is called when there is no access to the internet. Using Airplane Help requires associating the offline Help system with the RH_AssociateOfflineHelp program function.
