The following example demonstrates two problems with alternative=margintext in \setuphead: 1. When used with start/stop sectioning, text following the title may be set on the wrong line. 2. Without regard to the type of sectioning, margintext titles may spill over the left edge of the margin and beyond the page frame. \setuppapersize [letter] [letter,oversized] \setuplayout [location={middle,middle}] \showframe \setuphead [chapter] [number=no, alternative=inmargin] \setuphead [section] [ alternative=margintext, insidesection={\blank[-line]}, ] \starttext \starttitle [title={Problem description}] \bgroup \setupwhitespace[medium] \startparagraph This demonstrates two problems with \type{alternative=margintext} in \tex{setuphead}: \startitemize[packed,n] \startitem When used with start/stop sectioning, text following the title may be set on the wrong line. \stopitem \startitem Without regard to the type of sectioning, \type{margintext} titles may spill over the left edge of the margin and beyond the page frame. (Oddly, \tex{paperwidth} is less than the sum of \tex{makeupwidth} and the margin widths and distances for both letter and A4 paper.) \stopitem \stopitemize \stopparagraph \startparagraph With start/stop sectioning, the text following the section title may begin one line below the start of the title. That can be remedied if there is no whitespace between paragraphs with \type{insidesection={\blank[-line]}}, but the remedy fails when there is whitespace, and increasing the correction has no effect. With traditional sectioning, the text appears baseline|-|aligned with the heading, as expected. The the correction has no effect in any case with traditional sectioning. \stopparagraph \startparagraph It makes no difference in any test how the paragraphs are delimited—blank lines, \tex{bpar}/\tex{epar}, \tex{startparagraph}/\tex{stopparagraph}, or \tex{par}. \stopparagraph \startparagraph Tested with standalone beta 2017.07.17 00:20. \stopparagraph \egroup \page \startchapter [title={Start/stop sectioning}] \startsection[title={Mis\-cel\-la\-neous quo\-ta\-tions}] \startparagraph \input jojomayer \stopparagraph \startparagraph \input carrol \wordright{No indent no whitespace.} \stopparagraph \stopsection \bgroup \setupwhitespace[medium] \startsection[title={Miscellaneous quotations}] \startparagraph \input jojomayer \stopparagraph \startparagraph \input carrol \wordright{No indent medium whitespace.} \stopparagraph \stopsection \egroup \bgroup \setupindenting[yes,small] \startsection[title={Miscellaneous quotations}] \startparagraph \input jojomayer \stopparagraph \startparagraph \input carrol \wordright{Small indent no whitespace.} \stopparagraph \stopsection \egroup \bgroup \setupwhitespace[medium] \setupindenting[yes,small] \startsection[title={Miscellaneous quotations}] \startparagraph \input jojomayer \stopparagraph \startparagraph \input carrol \wordright{Small indent medium whitespace.} \stopparagraph \stopsection \egroup \stopchapter \chapter{Traditional sectioning} \section{Mis\-cel\-la\-neous quo\-ta\-tions} \input jojomayer \par \input carrol \wordright{No indent no whitespace.} \par No indent no whitespace. \par \bgroup \setupwhitespace[medium] \section{Miscellaneous quotations} \input jojomayer \par \input carrol \wordright{No indent medium whitespace.} \par \egroup \bgroup \setupindenting[yes,small] \section{Miscellaneous quotations} \input jojomayer \par \input carrol \wordright{Small indent no whitespace.} \par \egroup \bgroup \setupwhitespace[medium] \setupindenting[yes,small] \section{Miscellaneous quotations} \input jojomayer \par \input carrol \wordright{Small indent medium whitespace.} \par \egroup \showlayout \stoptext -- Rik
