This should not be possible. Org cannot recognize all LaTeX syntax. If you cannot preview it, Org does not understand it. IOW, it would be a poor experience if you preview something that doesn't exist, e.g., upon exporting the document. OTOH, nothing prevents an external library to allow previewing any LaTeX code (probably re-using AucTeX facilities). Regards, --=20 Nicolas Goaziou
