Viewing Inputs

The Inputs tab in Windows -> Actor I/O shows all actions that are targeting this actor. This tab is purely for debugging and overview purposes. You cannot edit or change actions from here. The "New Action" button is also disabled in this state. Use this to find actions that do something with this actor.

Each action has a magnifying glass at the end. If you click this button then the actor that is calling this action will be selected in the Level Editor, so you do not need to search for it manually.
