| off('deleteLeft')         | off(type: 'deleteLeft'): void         | off(type: 'deleteLeft', callback?: (length: number) => void): void |

| off('sendKeyboardStatus') | off(type: 'sendKeyboardStatus'): void | off(type: 'sendKeyboardStatus', callback?: (keyboardStatus: KeyboardStatus) => void): void |
| off('sendFunctionKey')    | off(type: 'sendFunctionKey'): void    | off(type: 'sendFunctionKey', callback?: (functionKey: FunctionKey) => void): void |
| off('moveCursor')         | off(type: 'moveCursor'): void         | off(type: 'moveCursor', callback?: (direction: Direction) => void): void |
| off('handleExtendAction') | off(type: 'handleExtendAction'): void | off(type: 'handleExtendAction', callback?: (action: ExtendAction) => void): void |
| off('selectByRange')      | off(type: 'selectByRange'): void      | off(type: 'selectByRange', callback?: Callback\<Range\>): void |
| off('selectByMovement')   | off(type: 'selectByMovement'): void   | off(type: 'selectByMovement', callback?: Callback\<Movement\>): void |

**变更影响**

以上接口的调用,有多个订阅回调时,可传入订阅回调函数只取消单个回调函数的订阅,当该参数不填写时,取消订阅对应的所有回调事件。

**适配指导**
