Brian, I was already aware of the Getting Started area. That was not helpful to me. I was wanting to know how to revert code in a branch back to an earlier revision but Getting Started does not cover that. So I did a search using key words to find this help. I got 0 matches. I then kept removing keywords until Mercurial was left and still 0 matches!
So no, your answer is not helpful. Your Support Search is not helpful.
