Shows the signals of the supernode of the current instance. This command is only available if you have double-clicked a subnode in the signal area, so that the signals of a subnode are currently being shown. In that case, this command returns to the parent node. In effect, if the current instance has been reached by double-clicking subnodes several times to walk down in the model hierarchy, this command is used to walk back, upwards in the model hierarchy.
Available when the signal area is showing the signals of another node than the top-level node.
