For my purposes I would like to have (free-standing) section numbers in the margins and no section headings---just the section text---immediately following (i.e., on the same line as) the section number. The following gets me close to what I would like
\hangsecnum
\counterwithout{section}{chapter}
\setaftersecskip{-1em}
but it leaves about an inch of horizontal space after the sec number/margin before my text begins. Larger and smaller values of the third command increase the space horizontally or vertically. Is there a way to have the section body immediately follow the section number on the same line using memoir
?
