Reference Keys

Reference keys are internal identifiers that the application assigns to objects. When you create a new object, the application automatically uses the name of the new object as the default reference key. It also makes sure that each reference key is unique. It's usually easiest to accept the default reference key. You can change the reference key before you save the object, but be sure to use a unique key.

Note: Reference keys are locale-independent. An object’s reference key doesn't change if it exists in multiple locales.
