pdflatex not an option anymore in TeX-command-list

For years I built tex into pdf with pdflatex; I just hit C-c C-c and there it was. But now having just rebuilt my system with Guix, I find that pdflatex isn't on the list of compilation commands. This is despite the fact that the command `pdflatex` works from the command line. Does anyone know where it went in auctex, and how to get it back?

I worked it out. I started in the customize menu and played around until I got the answer, then saved it to my :custom in use-package. `("pdflatex" "%(PDF)%(latex) %T -shell-escape" TeX-run-command nil t :help "Run pdflatex")` Now my whole use-package (straight) looks like this (including many defaults, which I should probably clean out): (use-package tex-mode :straight auctex :mode "\\.tex\\'" :custom (TeX-parse-all-errors nil) (TeX-suppress-ignored-warnings t) (TeX-command-list '(("pdflatex" "%(PDF)%(latex) %T -shell-escape" TeX-run-command nil t :help "Run pdflatex") ("TeX" "%(PDF)%(tex) %(file-line-error) %`%(extraopts) %S%(PDFout)%(mode)%' %(output-dir) %t" TeX-run-TeX nil (plain-tex-mode texinfo-mode ams-tex-mode) :help "Run plain TeX") ("LaTeX" "%`%l%(mode)%' %T" TeX-run-TeX nil (latex-mode doctex-mode) :help "Run LaTeX") ("Makeinfo" "makeinfo %(extraopts) %(o-dir) %t" TeX-run-compile nil (texinfo-mode) :help "Run Makeinfo with Info output") ("Makeinfo HTML" "makeinfo %(extraopts) %(o-dir) --html %t" TeX-run-compile nil (texinfo-mode) :help "Run Makeinfo with HTML output") ("AmSTeX" "amstex %(PDFout) %`%(extraopts) %S%(mode)%' %(output-dir) %t" TeX-run-TeX nil (ams-tex-mode) :help "Run AMSTeX") ("ConTeXt" "%(cntxcom) --once --texutil %(extraopts) %(execopts)%t" TeX-run-TeX nil (context-mode) :help "Run ConTeXt once") ("ConTeXt Full" "%(cntxcom) %(extraopts) %(execopts)%t" TeX-run-TeX nil (context-mode) :help "Run ConTeXt until completion") ("BibTeX" "bibtex %(O?aux)" TeX-run-BibTeX nil (plain-tex-mode latex-mode doctex-mode context-mode texinfo-mode ams-tex-mode) :help "Run BibTeX") ("Biber" "biber %(output-dir) %s" TeX-run-Biber nil (plain-tex-mode latex-mode doctex-mode texinfo-mode ams-tex-mode) :help "Run Biber") ("Texindex" "texindex %s.??"
