Hello developers, I use lyx for technical reports for several years (with great success and pleasure, thanks to you), but currently I still use Xemacs/pdflatex for beamer presentations.
Here a few remarks after a round trip when trying to turn a foo.tex file written in beamer class into foo.lyx: -------- one is about the optional arg to the \frame command \frame[plain]{\titlepage} -> \frame{[}plain{]}{titlepage} -------- The others all happen when closing a frame: \end{itemize} \end{columns}} % end frame \end{columns} -> } % end frame \end{itemize} -------- \column{0.45\textwidth} \end{columns} -> \column{0.45\textwidth\end{columns}}} } -------- In fact, the \column command (and the } closing the frame) belong to the preceding environment in the lyx code, e.g. layout Itemize remains open as no layout Standard appears before the ERT inset. layout Itemize [...] \begin_inset ERT status Collapsed \layout Standard \backslash end{columns} \end_inset It seems located inside the ERT, where it has no effect I guess. Sorry if this has been reported, is bugzilla appropriate for tex2lyx ? I can downsize this to a minimal two-slide example if needed. HTH -- Jean-Pierre
