Mostly for the sake of doing so, I am writing a presentation in ConTeXt. I thought that defining a start-stop would be a good way to split up slides. So I have something like:
\definestartstop[Slide][after={\break}]
...
\startSlide
\subject{Title}
\subsubject{Subtitle}
\stopSlide
My question is, given that every slide will have a title and a subtitle, is there a way to wrap the \subject and \subsubject up in the \definestartstop and provide the values when the start-stop begins?
I haven't found anything that is related to this and I know start-stops don't take arguments, so how might you do something like that? If I am going about the problem wrong, what would be the ConTeXt way?
