Alfred 快捷切换MacBook外接显示器横竖屏

参考用Alfred实现Mac OSX快捷旋转屏幕

硬件：MacBook Pro early 2015 （显卡ntel Iris Graphics 6100 1536 MB）
外接：Dell P2415Q （难得的23.8英寸的小尺寸4K屏，终于不觉得显示器发虚了）
系统：macOS sierra 10.12.4
软件：Alfred 3

Dell的这个显示器支架是支持旋转的，竖屏浏览文档、刷网页还是挺爽。但是切换横竖屏不想Windows有快捷键，不是很方便。本着偷懒的态度，搜到了简书上别人写的，发现不能用，自己找了下原始的applescript 稍微改了改，终于可以用了，分享出来吧，亲测可用。

只把几个关键部分的内容改成了中文就能用了，脚本作者已经在注释里面提醒了。如果系统语言是英文的，应该用上面文章里面的workflow应该就成。

下面是源码，懒得删注释了。

-- v1.2.2013-01-26 Thanks, Rich Graham for pointing out that display panels may have different layouts.  "button 1" below might need to change to "button 2" (or 3).
-- v1.1.2012-09-02 updated to work on 10.8 Mountain Lion.  Thanks, F. Parsons
-- v1.1.2010-08-01 updated to work with 10.6.4's reverted(?) display panel
-- v1.1.2010-04-08 updated to work with 10.6.3's revised display panel
-- v1.1.2006-03-01 updated to handle displays with the same name.
