If you click an object in the diagram, the most specific rule that
affects that object is selected in the tree and also has a blue
icon. This action is called rule-select.
Less specific rules that are applicable to the object also have the
blue icon, see figures Customized person nodes and Customized couple nodes.
In the diagram, the selected object is
surrounded by a selection box. Further objects to which the
selected rule applies are also surrounded by selection boxes.
Objects to which the rule applies, but for which more specific
rules might override the settings for that rule, are surrounded by
thin selection boxes.
If you change the selected rule, the change
is sure to affect all the objects shown with a (thick) selection
box; it might or might not affect the objects shown with a thin
selection box. Keep clicking a given graphic object to switch
between and select the rules marked with a blue icon.
