I've another question. What is the best way to deal with a big document in Context, to save each chapter in a single file and at the end include them in a "main document", or is there a better way?

It's no problem to keep everything in one document, but I like to split the file so that I can search easier (and some other advantages). Apart from that you can simply comment out the whole chapter at once if you use multiple files by simply commenting out the line % \input ch03-aliens in the main document for example. Besides that - ConTeXt is pretty slow. If you have a document with 300 pages, lots of graphics, ... and you only have to try out different parameters to fine-tune typesetting of one specific table, paragraph or figure, than it is easier to compile and show just a couple of pages than all of them at once. I usually use one file for style, one main file, multiple files (for example one per chapter) for content and another portion of files for figures. But it's all a matter of taste. ConTeXt doesn't really care about it. See chapter 2 in cont-eni.pdf. Mojca
