Finding scopes and it's conditions

[LukaszPol]

Hi, this is my first post here. How do I know the correct condition for a scope? For example:

primary_title = k_england

is invalid, but

primary_title = {
title = k_england
}

it's true.

How do I know the scope A (primary_title) need a specific condition B (title), or if the scope C accept conditions D or E. I know scopes don't accept direct ID values such as "k_england". The wiki have a cheat table, but unfortunately don't cover all scopes so I need some help to figure it out.

Thank you.
