@jsoref Thanks so much for raising this PR! I've had a look through the steps and I don't think we need a whole new procedural section for this. It seems like if you're in the blame view, you need to append a tilde to the hash in the URL to access the desired view—is that correct?

~ takes you one git commit in the past, a blame point ignore could be hundreds of commits in the past.
