Tab

If you use a tab in a panel, you can address the objects of the tab in a code directly without specifying the tab explicitly. If a shape within a tab searches for a shape within another tab panel, the shape is not found since the system only searches the panel that started the search.

If you use the syntax Module.PanelName:Shape, a shape in another tab can be found irrespective of the shape that started the search.
