Inspired by Aditya's "make a presentation in 40 commits" example,
I have defined my own environment for slides. A part of it looks
like this:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\startreusableMPgraphic{header:background}
fill OverlayBox
leftenlarged BackSpace
rightenlarged CutSpace
topenlarged TopSpace
withcolor OverlayColor ;
setbounds currentpicture to OverlayBox
enlarged max(BackSpace,CutSpace) ;
\stopreusableMPgraphic
\defineoverlay[header:background][\reuseMPgraphic{header:background}]
\define[2]\MySlide{\framed[
frame=off,
background=header:background,
backgroundcolor=orange,
width=\textwidth,
align=flushleft
]{#2}}
\definehead[slide][subject]
\setuphead[slide][
style=\ssb,
command=\MySlide,
color=white,
page=yes,
]
\starttext
\startslide[title={Slide One}]
\vfill
text
\vfill
\stopslide
\startslide[title={Slide Two}]
\vfill
text
\vfill
\stopslide
\stoptext
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
As you see, I am using \vfill to have the text vertically centered.
How do I setup the slide command to do that by default? I have tried
putting {before,after,beforesection,aftersection}=\vfill in various
combinations in \setuphead, but I cannot obtain the desired effect.
Related to the code above, I have another question: if I remove the
comma after page=yes, slides are not split into different pages. Is
it normal that a comma is required at the end of an argument list?

Thanks, that does it. I have noticed that in a few circumstances vertical alignment is not desired. How do I override the default settings on a per-slide basis? Something like: \startslide[title={...},insidesection=,aftersection=] (which does not work). >> if I remove the comma after page=yes, slides are not split into >> different pages.

Wait for others to chime in. Here's a workaround, though: \unprotect \setuphead [slide] [insidesection=\doifnot{\structureuservariable\c!align}\c!top\vfill, aftersection=\doifnot{\structureuservariable\c!align}\c!top\vfill] \protect Then you can use: \startslide [title={Slide Two}] [align=top] text \stopslide But probably there's a better way.

The attached example shows several problems. Test 1 and Test 3 show, that the \vfill at the beginning apparently adds a forced space (which is worse in Test 3 than in Test 1). Another problem is, that when the page needs to break (which is fine), the last page will not be centered. This is a logic consequence of the \vfill being after the section. Is there any other mechanism to center text on _all_ pages, no matter how often the sections or paragraphs need to get broken?
