Most of the interaction components have some common parts. They can be selected, meaning they share built-in functionality to transform the visual state (normal, highlighted, pressed, not available), as well as navigating to other selectble components via the keyboard or controller. These shared features are described in detail in selectable. (Selectable is the base class for many interactive components in the source code, after all, many basic functions are generic)

At least one unityevent will be called when the user interacts with a specific method and an interactive component. The UI system captures and logs all outgoing exceptions from the code attached to the Unityevent
