How TApplication processes CLX Help
TApplication in CLX provides two methods that are accessible from application code:
ContextHelp, which invokes the Help system with a request for context-based Help
KeywordHelp, which invokes the Help system with a request for keyword-based Help
Both functions take as an argument the context or keyword being passed and forward the request on through a data member of TApplication, which represents the Help system. That data member is directly accessible through the read-only property HelpSystem.
