Hi, A question about exporting: Is it possible to export two different subtrees in the same file to a different class? There are cases where it would be nice to be able to generate a document (say an article) from a single subtree in a file, and have other subtrees that contain short presentations that could be exported quickly to beamer, for example. Currently, the exporter seems to find the first #+LaTeX_CLASS in the file and use that for the entire file export, as well as exporting any subtree in the file, even if you define a separate LaTeX_CLASS under a specific subtree. I have looked into using export OPTIONS in subtrees for this, but have not hit on the right combination. Is this possible? Thanks, Jerry
