Thanks Wolfgang, Chen and Hans for your responses. I used Hans'
one ... it seems to work.
I'm actually trying to indent tables of contents by level. I want
each indent to match the start of the heading text of the previous
level, i.e.,
1 Chapter
1.1 Section
1.1.1 Subsection
1.1.2 Subsection
...
Title
in other words, the indent is not quite a fixed width per level.
The following complete example sort of does what I want (using Hans'
\setwidthof) but it will fail when the section numbers have more
digits than I have allowed for.
I have a feeling I should be using \setupcombinedlist[content]
[distance=1em] or something, but that puts an em space in front of
unnumbered chapters (titles) as well.
What I have done seems very ugly, surely there is a "proper" way?
