Relationship Field Tables
Unlike normal tables, relationship field tables are not shown automatically. To display them, click the cog icon next to the relationship, and then click Show.
If the mouse is currently in one of the relationship connection modes, you might find that instead of getting this menu, you get the pencil cursor. This is because MooD thinks you want to draw a connection. To get around this, on the Connect tab, click Field Copy. Because this is an invalid connection type for a relationship, mouse click will give you the menu.
