As you know, in plain TeX, \lineskiplimit tunes the vertical glue algorithm by specifying the minimum amount of space between the bottom edge of one line and the top edge of the following line. But in ConTeXt, it appears that \lineskiplimit is set to zero, at least in grid mode. We're using grid mode, and we have some occasional high ascenders, e.g. capital letters with diacritics on top. We have bodyfont size 8.1pt, and interlinespace = 9.3pt. We realize this is less than the recommended ratio of 1.2. Understandably, when those tall characters occur, we sometimes get a blank line above them. It looks like the \lineskiplimit would be violated if the 9.3pt interlinespace were enforced, so ConTeXt adds some space (analogous to \lineskip in TeX?). But since we're on a grid, more space has to be added in order to conform to the grid. All that makes sense, but we would like to be able typeset the lines closer together, and judge for ourselves whether it looks too bad. (When we used to typeset the same text at 8.1pt/9.3pt using mkii, blank lines did not occur.) Is there something similar to \lineskiplimit that we can tweak? I've been reading section 5.5 Line Spacing in the context ref manual, but I don't see anything there about changing a threshold analogous to \lineskiplimit. I tried setting \lineskiplimit=-2pt, but that caused a worse problem: a blank line across both columns, instead of just one. Thanks, Lars Version: mkiv luatex in Tex Live 2013.
