Re: [NTG-context] How to implement a changing navigation bar?

Hi all,

I use an overlay to implement a navigation bar in the left margin of a document. It seems to me that the processing of the overlay is done only once and not for every page again. In addition, the \lastpage is not available.

Does anyone know a solution? Maybe headers/footers are a solution. But how is absolute positioning accomplished with them?

Hi Stefan, header/footer is a solution but I use another \def\PageNavig{\setlayer[navbar][x=0cm,y=10cm]{\the\pageno}} \appendtoks \PageNavig \to \everypagebody for this task. Vit Zyka
