You can use the Object tab of this palette to give your object a name. Just type it into the name field, and then hit the Tab, Enter or Return key. You can change the name at any time; however, names must be unique. Named objects also appear in bold type in the Project window.
It is not always necessary to name objects. However, only named objects appear in the Host or Target fields on the spotlight or camera's Object Properties palette. Naming objects in a logical way can also help with the organization of large projects made of lots of individual parts.
