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.
\setuphead[slide][
  style=\ssb,
  command=\MySlide,
  color=white,
  insidesection=\vfill,
  aftersection=\vfill,
  page=yes]
insidesection, of course! 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).
No clue why that doesn't work. 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.
