chrome 谷歌浏览器扩展（4）- 快捷键

chrome浏览器自带的按钮都可以支持快捷键操作，我们自己开发的插件如何增加快捷键支持呢

答案当然是在清单文件manifest.json上搞事情，增加一个commands字段如下

"commands": {
  "_execute_browser_action": {
    "suggested_key": {
      "default": "Ctrl+Shift+F",
      "mac": "MacCtrl+Shift+F"
    },
    "description": "Opens hello.html"
  }
}

修改完后的完整内容如下

{
  "name": "Hello Extensions",
  "description": "Base Level Extension",
  "version": "1.0",
  "manifest_version": 2,
  "browser_action": {
    "default_popup": "hello.html",
    "default_icon": "hello_extensions.png"
  },
  "commands": {
    "_execute_browser_action": {
      "suggested_key": {
        "default": "Ctrl+Shift+F",
        "mac": "MacCtrl+Shift+F"
      },
      "description": "Opens hello.html"
    }
  }
}

重新加载，测试一下快捷键吧
