| const WA_HelpGroupWindow = WA_Dummy + 57; | 
When the active window has gadget help enabled, other windows of the same HelpGroup will also get GadgetHelp. This allows GadgetHelp to work for multi-windowed applications. As an alternative to WA_HelpGroup, you can pass a pointer to any other window of the same group to join its help group. Defaults to nil, which has no effect.
