Hi, I'd like to get access to the first letter of a chapter for the purpose of laying out the chapter heading, but I'm having difficulty with expansion. Here's my attempt: \def\MyChapterTitle#1#2{% \def\doMyChapterTitle##1##2^{% {\tfb ##1}##2 } #1 \doMyChapterTitle#2^ } setuphead[chapter][command=\MyChapterTitle] \starttext \chapter{Foo} bar \stoptext This doesn't work because the chapter title isn't expanded out before passing it to \MyChapterTitle. I know there is deeptextcommand but I need the chapter title during the layout of chapter number + title, so I need to use command instead of deeptextcommand. I attempted to get hold of the chapter title using the following \def\MyChapterTitle#1#2{% \def\doMyChapterTitle##1##2^{% {\tfb ##1}##2 } #1 \expandafter\doMyChapterTitle\expandafter{\fetchmark[chapter][first]}^ } but that doesn't seem to work either. Any ideas? Many thanks, M
