How to call latexmk in emacs, and jump to next-error

Question

I would like to use latexmk to compile my LaTeX documents in Emacs. Especially I need the Emacs functionality next-error, which is typically called with C-x `,

Answer 1

Adding %(mode) gives latexmk some more options like noninteractive if it is set so in auctex.

(add-hook 'LaTeX-mode-hook (lambda ()
  (push 
    '("Latexmk" "latexmk -pdf %(mode) %s" TeX-run-TeX nil t
      :help "Run Latexmk on file")
    TeX-command-list)))
