Hi: I read the context manual --- typography (by Taco Hoekwater) and found that if I want to enable hz and margin kerning, I should add a line like: \setupalign[hanging] however, when I read the style.pdf document, it said something like this: \setupalign[hanging,hz] and compiling a document with or without hz option will result in different line breaks. So I think one of the manuals should be corrected? Yue Wang
