Knowledge: Anyone any idea how "Set default knowledge field values" work?

[AdamUMC]

Hi there,

Does anyone know how the Knowledge Base "Set default knowledge field values" works? See attached screenshot for the exact field/functionality.

I was looking between UI Policies and Client Scripts, but cannot find anything related to this.
Anyone any idea? 

Thanks!

Adam

Seems that I have found what makes this working. It's the UI Page "kb_confirm_defaults".
