Hello Hans, thank you for contributing to solve my problem. I've tried your proposition : how can I get the content of the buffer afterward ? I've tried \getbuffer[Slide] with no success on MKIV beta that I've just updated. Does a buffer work only for verbatim content ? best regards, Pierre-François.
