i.e. what does the add-hook do? I think it reads, "When LaTeX mode is entered (e.g. by switching to a .tex buffer), push onto the TeX-command-list, the command "latexmk -pdf %s" where %s is the output of TeX-run-TeX."
Is that about right?
Hooks are a mechanism used all around Emacs in order to modify its behavior in a more granular way.
A hook is a Elisp variable holding a list of functions, to be called on some well-defined occasion. In this case, LaTeX-mode-hook holds functions that are loaded when the LaTeX mode is loaded.
The second says to add the "setq TeX-command-default "latexmk"" whenever TeX-mode-hook is entered. Is there a good reason not to just do the setq globally?
Sometimes such commands need to be issued every time a file is entered. Emacs does not set it globally as expected.
I'm an emacs noob, would you mind explaining a bit what this does?
