THelpAction Class

THelpAction is the base class for action objects that interact with the help system.
THelpAction = class(TAction);
class THelpAction : public TAction;
StdActns
THelpAction implements the common behavior for actions that work the help system. Each descendant class performs a specific help function. Do not use THelpAction directly in an application. Instead, use a THelpAction descendant such as THelpContents, THelpContextAction, THelpOnHelp, or THelpTopicSearch.
THelpAction ensures that the action is enabled as long as there is an application object to pass commands on to a registered help system. THelpAction descendants override the ExecuteTarget method to execute their specific help command.
