[...] My question is how to get a page from the document you‘re compiling repeated inside the same document.
I have tried to search both i-context.pdf and the wiki, but “mirror” and “repeat” seem to be bad options.
You can store each finished page in a box and access the content of the stored box afterwards.
Huge thanks for your reply and the code, Wolfgang. I have just checked “TeX for the Impatient” to understand what shipout methods and boxes were. I think I can barely grasp their meaning. Which are other usages for shipouts and boxes? I guess they are used to add pages in the final PDF document, but I don’t see which other uses they may have. BTW, “invokepagehandler” reads “invokepageheandler” in the following files from the ConTeXt Suite (I don’t know whether the first is the real source of the rest of them): * texmf-context/tex/context/interface/mkiv/i-imposition.xml * texmf-context/tex/context/interface/mkiv/context-en.xml * texmf-context/context/data/vscode/extensions/context/syntaxes/context-syntax-tex.json * texmf-context/context/data/textadept/context/data/scite-context-data-interfaces.lua * texmf-context/context/data/scite/context/lexers/data/scite-context-data-interfaces.lua * texmf-context/context/data/scite/context/scite-context-data-interfaces.properties Many thanks again for your help, Pablo
