By jhsrennie:

The Home button on the Nyxboard remote should take you to the home page, or at least this seems a sensible thing for it to do. That's why I've chosen to map to XBMC.ActivateWindow(Home). It does mean you can't use Home to go to the top of a list, but this seems a reasonable compromise. However I don't feel strongly about this.
