If the Properties view displays the settings for multiple objects, a drop-down field is added at the top of the Properties view. It displays the number of selected objects. Use it to select, whether the common properties of all selected modules should be displayed (All(x) ) or to select from the module types (<Module type>(x)). (x) is the number of modules (of this type). The properties all selected objects have in common are displayed.
If displayed settings for multiple selected objects differ, they display the string *Varies*.
Some of the common properties may not be allowed for common update. Therefore, properties that are not allowed for common update, are displayed as grayed out and can not be edited. All other properties can edited for all selected modules simultaneously. Thus, you can very comfortably re-configure many modules in your system.
