I think the following minimal example is giving an incorrect index. As ascii, the index comes out as a area 1 ellipse 1 see United Kingdom, area whereas the "see United Kingdom, area" should be indented the same as the ellipse second-level entry. It comes out okay if I delete the \index{area+ellipse} entry. (P.S. What's the setupregister key that puts the "see ..." entry in italic? I seem to have turned it off in my environment file somewhere. Oh, it's 'pagestyle', but then how can one separately set the style of the pagenumbers from the style of the "see ..."?) That aside, here's the example (run with 2014.05.17 MkIV): \setupregister[index][n=1] \starttext hello \index{area}area and \index{area+ellipse}area of an ellipse \seeindex{area+United Kingdom}{United Kingdom, area} \blank[3*big] \placeindex[criterium=all] \stoptext
