According to the description of \page in the contextgarden: "header - set header off temporarily"

But although this gives two pages numbered 1 and 2: \starttext \input knuth \page \input knuth \stoptext

This one does not honour the new page but typesets everything on page 1: \starttext \input knuth \page[header] \input knuth \stoptext

Is that as intended?

yes, it just changes a state, but you can use \page[header,yes]

It is not clear as yet. \starttext \input knuth \page[header,yes] \input knuth \page[header,yes] \input knuth \stoptext Here I get three pages, the first two without the last with header. That I understand. \starttext \input knuth \page[header] \page \input knuth \stoptext Both pages keep their header. \starttext \input knuth \page \page[header] \input knuth \stoptext Both pages keep their header. Should I conclude that the state change occurs if and onlyif when in the same macrocall a real pagebreak is realize? Because otherwise I do not observe a state change. Hans van der Meer

\starttext \input knuth \page[header] \page \input knuth \stoptext Both pages keep their header.

\starttext \input knuth \page \page[header] \input knuth \stoptext Both pages keep their header.

The header and footer keywords can be used when you want to hide header and footer texts on empty left pages before a chapter etc. in a doublesided document.

That is clear to me. But my question was: why do neither \page\page[header] nor \page[header]\page make any difference unless in these cases \page[haeder] is effectively a noop.

\setuppagenumbering[alternative=doublesided] \setuphead[chapter][page={yes,header,right}] \starttext \chapter{First chapter} \chapter{Second chapter} \stoptext
