Use this dialog to give your object a name. Simply enter the desired name and acknowledge by pressing "OK". The name of the object does not have to be unique. There may be objects with the same names in your pages.
The widget "Identifier" is only interesting for advanced users. You can give your object a unique identifier (UID) here, which no other object in this page may have. This unique identifier can be used to access the layer of this object directly from custom code. The identifier you specify here will be assigned to the layer of the object in the Hollywood script. See Code dialog for details.
