Hi,

Is there an #+STARTUP parameter to automatically display LaTeX
fragments?

If not, where do I have to look to add it?

Here is a patch to add `org-startup-with-latex-preview'. It should work
like `org-startup-with-inline-images'.

Thanks for the patch.  Did you already sign a FSF copyright assignment
or do you plan to sign one?

  http://orgmode.org/cgit.cgi/org-mode.git/plain/request-assign-future.txt

I cannot apply/accept the patch otherwise :(

Thanks,

Subject: [PATCH] Add a new startup keyword to preview LaTeX fragments

* doc/org.texi (Previewing @LaTeX{} fragments): Document the startup
  keywords which can be used to preview or not LaTeX fragments.
(Summary of in-buffer settings): Improve formatting and add an entry
for the variable `org-startup-with-latex-preview'.

* org.el (org-mode, org-startup-options,
  org-startup-with-inline-images): Add the variable
  `org-startup-with-latex-preview' which can be used to preview LaTeX
  fragments on startup. This variable is set to `nil' by default.

I'm glad to know other people like it too :)

Sure,

I knew I wanted something like the inlineimages STARTUP keywords. So,
I've searched in the source all references to inlineimages.

M-x moccur-grep RET inlineimages RET

I've found:
a custom variable: `org-startup-with-line-images'
an entry in `org-startup-options'

Then I've searched for `org-startup-with-inline-images' and found:
> (when org-startup-with-inline-images
>       (org-display-inline-images))

Then, I've searched the name of the function which toggled the latex
preview. C-h a latex RET then C-s preview in the *Apropos* buffer.

At this point I had everything and I just needed to copy what was done
for inlineimages and adapt it for latexpreview.
