SInce i cannot see you suffering ...

\definefontstyle [hanthethanh,htt] [htt]

\definebodyfont
  [10pt,11pt,12pt]
  [htt]
  [tf=Regular sa 1,
   bf=Sans sa 1]

\setupbodyfont[hanthethanh]
\setupfootnotes[n=3,align=normal,tolerance={verytolerant,stretch}]

So, we can mix {\bf whatever fonts} we want in a style like \htt.

You can add this code to cont-new.tex

\setupfootnotes[\c!uitlijnen=\v!normaal,\c!tolerantie=\v!soepel]

\def\setfootnotebodyfont%
  {\let\setfootnotebodyfont\relax
   \restoreglobalbodyfont
   \switchtobodyfont[\@@vnkorps]%
   \steltolerantiein[\@@vntolerantie]%
   \steluitlijnenin[\@@vnuitlijnen]}

Now you can say:  

\setupfootnotes[align=normal, tolerance={verytoleranr,stretch}]

Indeed. The new otr will give you more control over that. It is a tricky
rounding error problem and (imho) tex does not always give you the control
you need.

I tried the following:

==================== begin of file font-test.tex ==========================
\definebodyfont [14.4pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt] [rm] [ 
    tf=LexiconNo2RomanA-Txt8y,
    bf=LexiconNo2RomanC-Txt8y,
    it=LexiconNo2ItalicA-Txt8y,
    bi=LexiconNo2ItalicC-Txt8y,
    sc=LexiconNo2RomanA-Exp8y]

\definefontstyle [aa] [aa]

\definebodyfont [14.4pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt] [aa] [ 
    tf=LexiconNo2RomanB-Txt8y,
    bf=LexiconNo2RomanD-Txt8y,
    it=LexiconNo2ItalicB-Txt8y,
    bi=LexiconNo2ItalicD-Txt8y,
    sc=LexiconNo2RomanB-Exp8y]
==================== end of file font-test.tex ==========================

and the tex file looks like:

==================== cut here ==========================
\setupbodyfont [test]
\setupfootnotes[style=aa]

\starttext
\chapter{A SHORT STORY}
Once upon a time, in a distant
  galaxy called \"O\"o\c c,
there lived a computer
named R.~J. Drofnats.
\footnote{% 
Mr.~Drofnats---or ``R. J.,'' as
he preferred to be called---% error has been fixed!
was happiest when he was at work
typesetting {\it beautiful\/} documents.}
\stoptext
==================== cut here ==========================

it works more or less, but there are still two problems:

1) the chapter font is cmr12
2) the italic font in the footnote comes from \rm, not \aa as I expected

How can I please fix it?

Shouldn't this be [rm] to define an rm font?

Else you perhaps have to do a

\setupbodyfont[test,aa]

Groetjes,

You can take anything you want, but rm, ss tt hw and cg are kind of
predefined; so one can have hundreds of font collections

% interface=en output=pdftex

% first we define a new main font style 

\definefontstyle[footfonts,ff] [ff]

% then we define a (here quite simple) body font set that belongs to this
style

\definebodyfont[10pt,11pt,12pt] [ff] [tf=lbr sa 1]

% you want footnotes to use this style 

\setupfootnotes[bodyfont=footfonts]

% so let's test it: 

\starttext 

test test \footnote {test test} test test

\stoptext

% you have the lbr's i guess, but using more verbose names is better

then you need to define:

Re: call for help with context

[Han The Thanh]

Hans,

many thanks for the great hints -- it works now. But for completeness: how
can I define a new style like \bf, \it in a new family? For example I tried
a \zz style:

\definebodyfont [12pt,11pt,10pt] [aa] [ 
    tf=LexiconNo2RomanA-Txt8y,
    zz=LexiconNo2RomanD-Txt8y]

but when switching to \zz, it seems to go into an endless loop: I had to
use `killall pdfetex' to stop it.

you should add the sa 1 [scaled a 1 time the current bodyfont] otherwise it
gets the whatever-it-is design size

The number of families is limited in tex (which is quite annoying since
it's one of the reasons why macro(packages) are more complicated than
needed when it comes down to fonts). Families are kind of tricky anyway
since in math the fonts are resolved afterwards which means that one cannot
temporarily overload a family. 

In context, there are a number of predefined families
(tf,bf,sl,it,bs,bi,sc) and technically one can extend this list. One way is
to misuse a family that you would not use anyway, so using the bi slot fo
rinstance, but an alternative is to hitch hike on an existing one like: 

  tf=...,
  tfmine=LexiconFontWithAVeryLongAndFunnyNameEncodedInASpecialWayByThanh sa
1, 

This would behave like tfa etc, which is ok outside math; in the
bodyfontenvironment you could specify 'mine' as size 1 so that you could
say 'sa mine'].

Hans, I posted a mail on the list about footnote handling, about a
week ago, named "Still on footnotes", with two test files that show
the problems presented in the post. Were you able to pin down the
problems? Are they the same as the ones referred in this post?
