...
For example I would like to have footnote marker SansSerif.
You're lucky that currently i'm merging in the experimental multiple footnote and line notes modules (needed by idris cum suis); so adding a few additional keys was easy: \starttext \setupcolors[state=start] \setupfootnotes[textcommand=\high,textstyle=\ss\tx,textcolor=red] test \footnotetext{test} test test \note\ test test \footnotetext{test} test test \notesymbol[footnote]\ test \stoptext
If I would do it with the conversion key like this...
\setupbodyfont[4pt] \setupinterlinespace[line=45pt]
\definefont [FNfont][Sans at 10.5pt]\def\setfootnotebodyfont{\FNfont\setupinterlinespace[line=13pt]} \definefont [FNXfont][Serif at 10.5pt]\setupfootnotedefinition[style=\FNXfont]
btw, you can say: \definefont [FNfont][Sans at 10.5pt][interlinespace=13pt]
\defineconversion[HowAboutIt][\ss] \setupfootnotes[conversion=HowAboutIt,numbercommand=]
hm, this is not what conversion is meant for -) conversion is fed a number so you end up in a mix up of conversion and font switching and actully luck that you get something
... then suddenly the number in front of the footnote text becomes 4pt. If I do it without conversion... \setupfootnotes[numbercommand=] ... then the number in front of the footnote text is 19.5 -- as defined in FNfont.
That's why I felt the conversion key is not so reliable in this case.
a good observation -) Hans
