Hi, sorry for the potentially puzzling title. I try to figure out why \setuplayout[grid=yes] seems to insert a line break in a short formula. Is there a way of ensuring regular vertical alignment of the formula number without ‘split=line’ ? Many thanks for your help. %%% START \setuppapersize[A6,landscape] \enabletrackers[math.showmargins.less] \startsetups[math:penalties:mathincontext] \shapingpenaltiesmode \zerocount \widowpenalties 3 5000 250 100 \clubpenalties 3 5000 250 100 \stopsetups \setupformula [split=mathincontext] \starttext Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \setuplayout[grid=yes] \page Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \page Text \startplaceformula \startformula[split=line,numberlocation=overlay] c^2 = a^2 + b^2 \stopformula \stopplaceformula \disabletrackers[math.showmargins.less] \stoptext %%% END
