PowerScript has pronouns that allow you to make a general reference to an object or control. When you use a pronoun, the reference remains correct even if the name of the object or control changes.
You can use pronouns in function and event scripts wherever you would use an object’s name. For example, you can use a pronoun to:
Cause an event in an object or control
Manipulate or change an object or control
Obtain or change the setting of a property
