Here is a few screen dumps for Armored³ that describes the propagation editor.
The tab areas are live, so you can navigate through the different screens by clicking on the tabs.

In this last tab you will have the opportunity to specify the content of your propagation. The interface allows you to traverse the source application hierarchy and select the appropriate entities you wish to alter. You are also offered the opportunity to rename source entities when copying them to your new server(s).
