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 `,

Sorry I don't have the ability to comment, or I would just add this as a comment. Chris Conway's answer works, except that it should use TeX-run-TeX instead of TeX-run-command so that AucTeX knows to process the error messages.

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

It might also be wise to add something like

'("%(-PDF)"
  (lambda ()
    (if (and (not TeX-Omega-mode)
             (or TeX-PDF-mode TeX-DVI-via-PDFTeX))
        "-pdf" "")))

to TeX-expand-list and use "latexmk %(-PDF) %s" so that it will work in both pdf and dvi mode. Personally, I find it easier to use customize especially when you are experimenting.
