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.
