有什么办法git checkout上一个分支吗？ - Is there any way to git checkout previous branch?

问题：

I sort of want the equivalent of cd - for git. 我有点想要cd - git。 If I am in branch master and I checkout foo , I would love to be able to type something like git checkout - to go back to master , and be able to type it again to return to foo . 若是我在branch master而且我签出了foo ，我但愿可以输入git checkout -以返回到master ，并可以再次键入它以返回到foo 。

Does anything like this exist? 像这样的东西存在吗？ Would it be hard to implement? 实施起来会很难吗？
