如何在Slate中为触发事件分配热键

// 配置文件示例

// 绑定热键 Command + Option + Left 到将当前窗口移动到左边的屏幕
slate.bind("cmd:alt:left", function(window) {
  window.doOperation(slate.operation("move", {
    "x": "screenOriginX",
    "y": "screenOriginY",
    "width": "screenSizeX/2",
    "height": "screenSizeY"
  }));
});

// 绑定热键 Command + Option + Right 到将当前窗口移动到右边的屏幕
slate.bind("cmd:alt:right", function(window) {
  window.doOperation(slate.operation("move", {
    "x": "screenOriginX+screenSizeX/2",
    "y": "screenOriginY",
    "width": "screenSizeX/2",
    "height": "screenSizeY"
  }));
});

// 设置默认的窗口布局
slate.default(function(window) {
  window.doOperation(slate.operation("move", {
    "x": "screenOriginX",
    "y": "screenOriginY",
    "width": "screenSizeX",
    "height": "screenSizeY"
  }));
});
