Is it possible to select a range of code and open it in GitHub using Magit? I use the browse-at-remote package for this, but I wonder if this could be done from Magit. I'd like to navigate both from code selection and from a commit diff. Also, I'd like to be able to browse the master branch, even if I'm in a feature branch. Right now with browse-at-remote I have to manually replace the branch name with master in the GitHub URL.
