I have never understood the purpose of \lyxframe and \lyxframeend when
the standard \begin{frame} and \end{frame} are available.Conceding my almost complete ignorance on this topic, wouldn't it be better to for LyX to use standard Beamer / LaTeX commands whenever possible? This would seem to improve interoperability with users of "pure" latex, as well as to adhere to the general principle of keeping things simple and not introducing complications that are not needed.
