Sure, but my problem is that I have a document with five or six chapters. Each chapter is included in files which are named for instance
	chapter-1.tex
	chapter-2.tex
and so on.  Then my file main.tex contains the lines 
	\input chapter-1.tex
	\input chapter-2.tex
and so on, in order to typeset the whole document. But now I don’t know how to sync the PDF file with the source files chapter-1.tex, chapter-2.tex, etc., in order to correct mistakes or mistypings when I discover them in the PDF file.
Clearly, the main file and these files are residing in the same directory.

Is there a way to tell context to look into the directory where the main file and my chapter files are?

Thanks a lot for your attention.
