To edit the parameters of one or more sites, sectors or radios you first need to select the entities you are interested in.

Once you have made a selection, the properties of the selected items appear in the Properties Window:

Site Properties

You can use this window to edit the properties of the selection directly. Simply click on the appropriate field and type in the new values. Entries with a "+" are expandable; in the screen shot above the Flags property of a Site has been expanded to show the values of the various Flags that have been associated with this site.
