Description
Pass Help request directly to engine.
The RTL Help System calls CallWinHelp when it receives a Windows-style Help request that cannot be generalized as a Topic-based or Context-based request. CallWinHelp should pass the request directly to the Windows winhelp() API or to a functional equivalent.
CallWinHelp should return true if it was able to handle the request.
