The Object Editor lists all the objects in a scene. Each object has a unique identifier and a type which determines its appearance and capabilities. From the Object Editor you can also access global objects and groups.

Right-click on All objects and choose Add an object from the menu or from the ribbon.
Edit an object by double-clicking it.

Right-click an object or use the ribbon to access more options. For example, you can edit an object initial variables (i.e. variables created when the object is created).

There is a sub-menu to edit automatisms:

Automatisms used by the object are displayed at the top of the menu. To edit an automatism, simply click on it. To add or remove an automatism, use the additional menu items displayed in the bottom part of the menu.
