Is this what you mean by the quick reference? Class
Here is a link to visibility specifiers in the Verse Glossary
Here is how you do visibility specifiers:
# Class is public in this module
example_class := class<public>():
# Prop is private
Prop1<private>: float = 0.0
# Prop is protected
Prop2<protected>: float = 0.0
# Prop is public (also default)
Prop3<public>: float = 0.0
