Could someone on the list > please give me a hand? If you look inside `org-beamer--format-block', it uses `org-beamer-environments-default' and `org-beamer-environments-extra' to format the blocks. See docstring for the latter for details. The code responsible for LaTeX block generation is (when (nth 2 env-format) ; when we non-column block (concat (org-fill-template ...) ; opening \begin lines contents ; block body ... ; block closing \end lines ) org-fill-template is using the template from the `org-beamer-environments-*' replacing %-chars as described in the docstring. In order to handle CUSTOM_ID property, you can (1) Introduce a new %-substitude to be handled in org-fill-template call. It will insert block ID. (for example, using `org-beamer--get-label') (2) modify `org-beamer-environments-default' to insert label appropriately.
