Enables listening for combination key events. When a combination key event that meets the specified conditions occurs, **keyOptions** will be passed as an input parameter to **callback**.
This is a system API.
Enables listening for combination key events. This API uses an asynchronous callback to return the combination key data when a combination key event that meets the specified condition occurs.
| type | string | Yes| Type of the key input event to listen for. Only **key** is supported.|
| keyOptions | [keyOptions](#keyoptions) | Yes| Key option, which specifies the condition for combination key input.|
| callback | Callback<KeyOptions> | Yes| Callback used to return the result.<br> When a key input event that meets the specified options occurs, **keyOptions** will be passed as an input parameter to **callback**.|
| callback | Callback<KeyOptions> | Yes | Callback used to return the combination key data when a combination key event that meets the specified condition occurs.|
| callback | Callback<KeyOptions> | No | Callback for which listening is disabled. If this parameter is not specified, listening will be disabled for all callbacks registered by the current application.|
**Example**
```js
letleftAltKey=2045;
lettabKey=2049;
// Disable listening for a single callback function.
| preKeys | Array | Yes| Array of precedent keys. This parameter can be left empty. There is no requirement on the sequence of precedent keys.|
| finalKey | Number | Yes| Final key in the combination key. This parameter cannot be left blank.|
| isFinalKeyDown | boolean | Yes| Whether the final key is pressed or released. By default, the final key is pressed.|
| finalKeyDownDuration | Number | Yes| Duration for pressing the final key. By default, there is no requirement on the duration.|
| Name | Type | Readable | Writable | Description |
| --------- | ------ | ---- | ---- | ------- |
| preKeys | Array\<number> | Yes | No| Front key set. The number of front keys ranges from 0 to 4. There is no requirement on the sequence of the keys.|
| finalKey | number | Yes | No| Final key. This parameter is mandatory. A callback function is triggered by the final key.|
| isFinalKeyDown | boolean | Yes | No| Whether the final key is pressed.|
| finalKeyDownDuration | number | Yes | No| Duration within which the final key is pressed. If the value is **0**, the callback function is triggered immediately. If the value is greater than **0** and the value of **isFinalKeyDown** is **true**, the callback function is triggered when the key press duration is longer than the value of this parameter. If the value of **isFinalKeyDown** is **false**, the callback function is triggered when the duration from key press to key release is less than the value of this parameter. |
