Assign an existing action asset as project-wide
To assign an existing actions asset as project-wide, do one of the following:
- Go to Edit > Project Settings > Input System Package
- Drag the asset from your Project window into the Project-wide Actions field.

The Input System Package Project Settings with no project-wide actions assigned displays a button to create and assign a default project-wide action asset
or:
- Select the Asset in your Project window
- In the Inspector window, select Assign as the Project-wide Input Actions.
Only one Actions Asset can be assigned as project-wide. If a different asset was previously assigned as project-wide, it becomes unassigned.
