Where did you find it in the manual? Did you look at this section? 12.6.2 Header and sectioning structure There is mentioned the `org-export-latex-class' variable. Then you can do C-h v org-export-latex-class RET to get information about the variable, and see in what customization group it belongs. >> I looked >> there.

Just do `C-h v' after a variable's name, it will describe the variable. >From the buffer containing the description, you can follow a link to customize it. >>> 2.

No. If you change things in Org Elisp files, you need to reload Org with M-x org-reload RET HTH, PS: While insisting on getting an answer, please be extra careful of having a readable email ;) -- Bastien
