Thanks
sorry for incomplete example
the code below shows the problem better:
\setupinteraction[state=start]
\definenote[Mynote][location=text,before={},]
\setupnote[Mynote]
[location=left,
textcommand={\tfa \raise 0.2ex\hbox},
]
\definefont[highfont][name:ibmplexsansbold*default at 10pt]
\definehighlight[newhigh][color=darkblue,style=highfont]
\starttext
\input{knuth} \Mynote{refrence}
\startitemize
\item \newhigh{\input{knuth}\Mynote{refrenceTwo}}
\stopitemize
\placenotes[Mynote]
\stoptext
as you can see the note number has same style all over the document.
but i want it to have style base on current font
and if the font changes, the style should change, while maintaining the ratio of sizes(i.e., at the half of current font).
i attached the resulted pdf
