Handles SHIFT+F1 Help within the application.

afx_msg void OnContextHelp( );

You must add an ON_COMMAND( ID_CONTEXT_HELP, OnContextHelp ) statement to your CWinApp class message map and also add an accelerator table entry, typically SHIFT+F1, to enable this member function.

OnContextHelp puts the application into Help mode. The cursor changes to an arrow and a question mark, and the user can then move the mouse pointer and press the left mouse button to select a dialog box, window, menu, or command button. This member function retrieves the Help context of the object under the cursor and calls the Windows function WinHelp with that Help context.
