Thoughtbot: git checkout and see

url: http://robots.thoughtbot.com/post/26417669058/git-checkout-and-see

Handy shortcut for both git checkout [branch_name] of git checkout - which will take you to last branch used. So if you are going between two branches, you can quickly toggle between them without typing their names.

Apparently "cd -"  works the same for directories. I did not know that.

I'm also a fan of adding the following to my ~/.gitconfig:

[alias]
 st = status
 ci = commit
 co = checkout
 br = branch

Nice and short "git co -" after that.
