# Edit Observable\Controllable Events

From the Project Menu, select Edit Observable\Controllable Events or from the toolbar, click on the Edit Observable\Controllable Events button . This will open the Edit Observable\Controllable Events window. This editor will allow the user to specify the controllable and observable events for each defined decentralized supervisor.

The decentralized supervisor's name displayed in the window can be changed to show other defined decentralized supervisors using the drop-down box.

The Add Controllable Event button and the Add Observable Event button are used to move the selected controllable\observable events to the decentralized supervisor currently displayed in the window.

The Remove Controllable Event button and the Remove Observable Event button will remove the selected controllable\observable events in the window from the decentralized supervisor currently being viewed.

Changes made here take effect immediately, updating the project's data structures on the fly.
