I've been working on branch A. My work there is not finished, but I need to switch to branch B for a while. It looks like stash is the command to use. I've found a number of references showing how to use stash to save your changes, but I'm a bit confused. All of the references say something like, when you're ready to go back, just do git stash pop. They don't, however, tell me if I need to switch back to branch A before doing that, though.

So, do I manually go back to branch A before running stash pop, or do I stay in branch B, and the actual act of running stash pop will send me back to branch A where I left off with it?
