Hi Hans,
sorry for contacting you off-list. But the publishing-house I am 
working for at the moment needs to know the answer to my "Index 
design" question today.
They have a series of books with a given index (register of keywords) 
designed as described below.
This design was set in the past with 3B2, and now is the question: is 
it also possible to set it (in this strange way) with ConTeXt?
Please see my description below (hope gets it's clear):
Is it possible, in an index, not to have single letters as separators
(here "a", "w") in a dedicated line, but instead only the first letter of
the first entry with "a" or "w" set bold?
See this minimal example:
\setupoutput[pdftex]
\starttext
\chapter{First Chapter}
Some text...\index{word}
\section {First Section}
Some text...\index{word}
Some text...\index{another entry}
Some text...\index{ansi}
Some text...\index{another entry}
\page[yes]
\completeindex
\stoptext
Here I would like to have only the first letter of the index entries
"another" and "word" in the index to be set bold.
