A more useful (from a user perspective, I do not know about the coding) solution would be a command to snap to the nearest grid line (up or down, half or whole step). But both your count and my \snapto suffer from a common problem. Both are likely to leave different amounts of space before and after the block. A more evenly balanced approach is to compute the height of the block plus the vertical space by which it should be set off plus the vertical space needed to reach a grid-line or half-grid and, if the block stays on the page, split the difference top and bottom. If the block does not stay on the page, some portion with the top offset must be calculated and placed on the page if it otherwise meets widow/orphan tests. -- Rik ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

I need to decide whether to - turn off grid snapping and adjust every single quotation or - turn grid snapping on, benefit from line correction most of the time and manually adjust the cases where a quotation is across a page boundary It depends on the texts I'm working on. This question reminds me the chapter about line profiling in the "Still" manual. There's no general, fully automated solution. > It would be nice to have an alternative that does not have that > limitation. > Hans talked about that at the last ConTeXt Meeting. If I understand well, it's very hard to calculate how much of the vertical space of the page TeX has used. And once it flushes the page, it frees the memory and forgets about it. Add inserts like footnotes to the problem and it gets really hard.
