### Contributing new retargetable actions

The workbench is not the only plug-in that can create retargetable actions. Your plug-in can define its own retargetable action, so that views and editors within your plug-in can share the same menu actions. There are two ways to contribute retargetable actions from your plug-in:

- An editor can define a retargetable action for which the editor and related views can hook handlers. The action is only available in the menu bar when the editor is open.
- An action set can define a retargetable action for which editors and views can hook handlers. The action will be visible as long as the action set is visible, but it will only be enabled if the active part has hooked a handler for the action.

This mechanism is useful for providing tight integration between editors and related views. For example, a content outline view can implement a handler for an action defined by its associated editor.

The readme tool example demonstrates both of these techniques.
