\setupbackgrounds [rightpage] [...] Thanks, Mojca, for your ideas! Special thanks to Hans, whose solution seemed efficient and worked like a charm (after I made one minor fix). I have attached to the end of this message code that works well on *either* right pages *or* left pages. Now I'd like to extend the code so that it would work on *both* kinds of pages. But my experimentation has raised the following questions:
1. When I change the \setupbackgrounds [page][background=thepage] in the code shown below to \setupbackgrounds [rightpage] [background=thepage], I expected that the left page would have no header and the right page would have the appropriate header. However, when I do this, I get two superimposed headers with different lengths on right pages (and nothing, as expected, on left pages). Why do I get *two* headers on the right page? 2. I also do not understand \startsetups command, which I could not find in the ConTexT manual or in the online summary of ConTexT commands. It looks like the purpose of this command is to put a wrapper around the \setlayerframed command so that it can be used in the \setupheadertexts command. Is this right? Also: a. I guess that I don't understand why the \setlayerframed command could not be used directly in the \setupheadertexts command: why do we need the wrapper? b. And why this particular wrapping command? (\startfoo ... \stopfoo doesn't work.) c. Also, I am assuming that the colon is simply part of the name assigned to this setup and has no other significance: is this right? 3. So, my guess (once problem 1 is fixed), is that I will define *two* layers (one for right pages and one for left pages), and do a \setupbackground [rightpage][background=therightpage] and a \setupbackground[leftpage][background=theleftpage]. But I don't know what to do inside the \startsetup ... \stopsetup. Do I have a pair of \setlayerframed statements? Do I surround this pair with something like an if onRightPage ... if onLeftPage statement? Or do I put the if-then statements *inside* the \setlayerframed statement? Thanks for any help...
