From what I can find, most online resources(whether it be lectures or textbooks) tend to be introductions that conclude with a construction of a swarzchild metric. While research papers are obviously way more advanced.

Do you have any recommendations for something in the middle? Also, any general advice for finding resources in the middle? In the past I have always just looked for books commonly cited in dissertations and papers.

Hey, I have relatively recently started using Emacs and was wondering if there are any particular packages, personally made Commands, key-binding, etc that you find useful for writing in LaTeX.
