I don't think this is documented anywhere that I've found, but

   git checkout -

checks out the previous branch you were on, similar to cd -

Big fan of git-aliasing this to `git back`. I actually use it a ton and that small amount of extra chars plus the "-" makes a pretty decent difference for me.

Speaking of extra characters, I'm pretty far in with the `git` commands. `git checkout` -> `g c`, `git status` -> `g s`.

I usually do `g c -` but I guess `g back` wouldn't be bad.
