Hi John,

Wolfgang, thanks - but this does not seem to fix the problem. The
"last page" appears opposite page 3 instead of opposite page 1.
To be clear, I am looking for a way to specify that content is to be
placed on the outside of the cover, i.e. printed on the same side of
the same sheet as page 1, when "arranged".
Could you try the following page brake method.
\unprotect
\installpagebreakhandler {newquadruple}%
  {\ifdoublesided
     \!!counta\realpageno
     \!!countb\realpageno
     \advance\!!counta 4
     \divide\!!counta 4
     \multiply\!!counta 4
     \advance\!!countb 1
     \advance\!!counta-\!!countb
     \executepagebreakhandler\v!yes
     \dorecurse\!!counta{\executepagebreakhandler\v!empty}%
   \fi}
\protect
...
...
\setuppapersize[A5][A4]
\setuparranging[2UP,rotated,doublesided]
\setuppagenumbering[alternative=doublesided]
\setuplayout[margin=0pt,width=fit]
\setupbodyfont[16pt]
\starttext
\dorecurse{11}{\input tufte \par \input knuth \par}
\page[8]
\page[8] is useless in this example because you're already beyound
the eight page and the argument is useless in this case.
\page[quadruple]
\page[newquadruple]
Well, this worked, thank you!
I can safely say I would not have found that on my own...
Could I trouble you for a version to take me to the page *before*,
i.e. the inside back cover? I now realise I may need to put content
there too, and if not I can just do another \page to get to the
outside back cover.
\unprotect

\installpagebreakhandler {beforequadruple}%
 {\ifdoublesided
    \!!counta\realpageno
    \!!countb\realpageno
    \advance\!!counta 5
    \divide\!!counta 4
    \multiply\!!counta 4
    \advance\!!countb 2
    \advance\!!counta-\!!countb
    \executepagebreakhandler\v!yes
    \dorecurse\!!counta{\executepagebreakhandler\v!empty}%
  \fi}

\protect

\setuppagenumbering[alternative=doublesided]
\starttext
\showframe
\subject Front Cover

\dorecurse{10}{\input tufte \par}
%\dorecurse{8}{\input tufte \par}

\page[beforequadruple]

Imprint

\page

Back Cover

you need --arrange only for documents with a table of content, indices ...
OK, but my real document *will* have these - this was just a minimal
example. Originally I wanted to put the arrangment commands outside
the document, but I then put them inside too in case it helped.
You could use modes for a imposed and a normal document.

\startmode[fold]
\setuppapersize[A5][A4]
\setuparranging[2UP,rotated,doublesided]
\stopmode

\startnotmode[fold]
\setuppapersize[A5][A5]
\stopnotmode

and process it with

texexec --arrange --mode=fold mydocument

and

texexec mydocument
