Right click on a state, then select *Refactor → Group States Into Composite*.
Rename the new composite state to *LightSwitch*.
| No errors occur. The states are wrapped in a compostite state named *LightSwitch*. | %{color:red}open% | | 12.1.1 | Simulate | Run simulation. | The behavior of the refactored model is equivalent to its behavior before refactoring. The composite state *LightSwitch* is highlighted in red (active). | %{color:red}open% | | 12.2 | Extract subdiagram | Select composite state *LightSwitch*.Right click, then select *Refactor → Extract Subdiagram*.
Hover over the subdiagram decorator in the lower right corner of the *LightSwitch* state.
Click on the subdiagram decorator.
| No errors occur.Subdiagram extraction leads to a normal-looking *LightSwitch* state, but with a subdiagram decorator in the lower left of state's box.
Hovering over that decorator shows a preview image of the subdiagram.
Clicking the decorator opens the subdiagram in a new editor tab.

Select the main region and paste the copied state (Ctrl+V or Cmd+V).
Hover over the subdiagram decorator in the lower right corner of the *Copy_1_LightSwitch* state.
Click on the subdiagram decorator.
| The copy state's name is *Copy_1_LightSwitch*.Hovering over that decorator shows a preview image of the subdiagram.
Clicking the decorator opens the subdiagram in a new editor tab.

The state *LightSwitch* state is highlighted in red. Transitions between *LightOff* and *LightOn* can be observed in the new editor tab mentioned in T12.2. | %{color:red}open% | | 12.3 | Inline subdiagram | Select the *LightSwitch* state.Right click, then select *Refactor → Inline Subdiagram*.

Right click on the state
Refactoring | Fold Outgoing Action should be disabled | %{color:red}open% | | 12.12 | Toggle alignment | Create a new statechart model.
Delete the state that has been created.
Add an orthogonal state (see the palette on the right).
Ignore any errors.
Right-click on the state and select *Toggle Subregion Alignment* in the shown context menu.
Repeat the last action.
| An orthogonal state without a name is added to the statechart.Its subregions *r1* and *r2* are horizontally aligned.
Toggling the subregion alignment toggles between horizontal and vertical alignment of the subregions.
