| Parameters          | Description                                                                                                                                                         |
|---------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `event_id`          | Specifies the event ID. Refer to the list of key events in the [EventIDs document](../../../key-events/key-events/), and the `#define KEY_events` in `gauges.h`. |
| `value0` - `value4` | Specifies up to 5 additional integer values. Set this to zero if it is not required.                                                                                |

##### Return Values

The function returns an ERR, which is usually ignored. If the event requested is not appropriate, it will simply not happen.

 

##### Example

``` wasm
trigger_key_event_EX1(KEY_ELECTRICAL_CIRCUIT_BREAKER_TOGGLE, 1, 1);
```

 

##### Remarks

You do not need to supply all 5 possible arguments, only those that are required for the key event being processed. Events triggered in this way will have the `SIMCONNECT_RECV_ID_EVENT_EX1` ID.
