I can't find answer to some questions about scripting in papyrus:

1- I can't find a function to Get equipped armor on an actor. I'm starting to think that is just not implemented

2- With "self" keyword i can point to the script instance, but if a want to point to the reference running the script, how can i do it?

3- Is there a way to set a default value for a properties that is not basic type (like a "keyword"), in a script that is not assigned to a reference? That will be useful for scripts that must be assigned to many refs, that use Keywords

3b- Alternatively, there is a function to Get Form by ID? So i can use it in question 3
