Blueprints, the basics

Let the player press H to hide the dialogue box. A player's gesture is an Input Action: give the skeleton's Hide a keyboard binding H and the box hides without touching a blueprint, but pressing H again does not bring it back. What happens on a press is written in a blueprint: first decide which one (App logic hears it on every page, Dialogue only during the story), then open Dialogue's logic and replace Hide Dialog with Toggle Dialog Display. Finally, find the reference for every node with F1.
