Action RPG Inventory System

Well I must say I really appreciate this work… especially for a noob. I am looking for the blueprint that holds the controls… ie E to interact. I have some other things I need to add, and one of them is also attached to E, I put what I needed into the Inventory Player Character, under Event Graph. but that was completely empty, until I added my stuff. I would like to keep these blueprints together in the same place. Thanks in advance for all help.
