3. Using only \mathlabeltext with \setuplabeltext is also more consistent with the current \labeltext that works with \setuplabeltext.

Sorry, I did 3 typos in my previous post. — First typo: 3. Using only \mathlabeltext with \setupmathlabeltext is also more consistent with the current \labeltext that works with \setuplabeltext. — Second typo:

\define\function{\dosingleempty\dofunction} \def\dofunction[#1]#2{% \iffirstargument

\doifelse{#1}{limop}{\mathop{\mathlabel{#2}}}{\mathop{\mathlabel{#2}}\nolimits}

\else \mathop{\mathlabel{#2}}\nolimits \fi} \define\function{\dosingleempty\dofunction} \def\dofunction[#1]#2{% \iffirstargument

\doifelse{#1}{op}{\mathop{\mathlabel{#2}}}{\doifelse{#1}{limop}{\mathop{\mathlabel{#2}}}{\mathop{\mathlabel{#2}}\nolimits}} \else \mathop{\mathlabel{#2}}\nolimits \fi} Plus these 2 definitions were not supposed to be in this post (I forgot to remove them during my tests). Nevertheless Hans could had them as well in math-ini.mkiv if he thinks the user should have access to this \function command, which is the ConTeXt version of the well known \operatorname and \operatorname* command in LaTeX. It provides: \starttext \startformula \function{lim}_{x\to a} f(x)\quad \function[op]{lim}_{x\to a} f(x)\quad \function[limop]{lim}_{x\to a} f(x) \stopformula \stoptext — Third typo:

\definemathcommand[arsinh][op]{\mathlabel{arsinh}} \definemathcommand[arsinh][nolop]{\mathlabel{arsinh}}
