+* group rather than the selected objects.  
+* Bindings are: 
+* <ul>
+* <li>action: a method to be invoked on the bound display group.
+* If the argument aspect is bound, the method must take 
+* one argument.  Otherwise, the method must take no arguments.</li> 
+* <li>argument: the attribute of the selected object(s) (possibly 
+* from a different display group) that will be used as an argument 
+* to the action method</li> 
+* <li>enabled: a boolean property that determines whether
+* the controlled component is enabled</li>
