UI components can define the associations between UI controls and help contexts,
           either statically or dynamically.
            
        
                - When defined statically, the effective help context changes only when the user
                    explicitly requests context-sensitive help, that is, when the context-sensitive
                    help trigger is activated.
- When defined dynamically, the effective help context changes whenever the user
                    activates any UI control with a dynamic context association, for example, selecting a
                    menu option, moving from one page to another in a dialog, and so on.
That distinction is significant when the Help view is visible.
            
                - When the context association is defined statically, context-specific content
                    shown in the Help view remains unchanged, regardless of the user’s action,
                    unless the user explicitly requests context-sensitive help, for example, by pressing
                    F1.
- When the context association is defined dynamically, context-specific content
                    shown in the Help view is updated automatically, whenever the user activates a
                    UI control.
All help contexts are defined and subsequently identified by a help context ID.
           The Eclipse help system uses help context IDs to locate matching
           org.eclipse.help.IContext objects, which represent the context-specific help
           content.
