Hi, I am wondering how others manage a large list of reference labels in ConTeXt. I use Vim as an editor and it supports ctags. ctags is a utility that is basically for supporting tags in programs (initially only for C, and hence the name), but can be used relatively easily with LaTeX. Basically, ctags creates a tag file with the format <tag-name> <tag-file> <tag-regex> (for details see http://ctags.sourceforge.net/FORMAT) Suppose I have a bunch of references all starting from eq:. Then inside Vim, I can type eq: and press ^X^T for Vim to search for the tags file with everything starting with eq: and I get to see all of them in a pop up menu. I can choose which ever label I want and continue. Further I can press ^] on a tag, and Vim jumps to the location of the tag, something like a hyperlink within the editor. I find both these features very useful while working for files with more than 50 tags. Creating a tag file for LaTeX is easy, since in LaTeX all labels are created using \label{....}. So, you can instruct ctags (the program) to search the file for \label{...} and store the first argument to the tags file. However, taking this approach with ConTeXt is almost impossible. Since the label is tied to the environment that creates it, it is impossible to parse. There is no way a reg-ex can determine if mylabel in \startproblem[mylabel] is an optional argument or a label. So, the only way to really get the label is through TeX itself. The tui file has some information, but it can be very hard to parse. A typical tui file has enteries like c \mainreference{}{cite-nsf-193}{2--0-2-4-2-0-0-0--9}{11}{MarschakRadner:1972} c \mainreference{}{fnt:f:2}{2--0-2-4-1-0-0-0--8}{10}{} c \mainreference{}{sec:prelim}{2--0-2-4-1-0-0-0--8}{10}{{C.4.1}{Preliminaries}} where the first two are auto-generated, while I only want the user entered tags to be stored. Suppose, one is willing to have the extra overhead of parsing every mainreference in the tag file. I can get the first two pieces of information for the tag file, the name of the tag and the file that it is in. But how do I get a regex (or linenumber) of where the tag is located in the file, so that ^] takes me to that tag. I can not figure out a regex which will take care of every case. Is there some other way to proceed? What are those other numbers in \mainreferece, do they contain any information about the line in the source file that generated the tag. And more generally, what do others do to keep track of labels in large projects. Aditya
