[NTG-context] Define a new command from the command \periods[n]

Hi, Is it possible to redefine the command \periods[n] to have a line that goes from the end of the word to the edge of the page without having to play on the number n ? Regards, Fabrice \starttext \startitemize[a][stopper=),style=bold] \item $x\mapsto -x^2+x+1$ : \periods[66] \item $x\mapsto 2x^3+4x-7$ : \periods[65] \item $x\mapsto x^2-3$ : \periods[70] \item $x\mapsto \frac{x^2+x}2$ : \periods[72] \item $x\mapsto (x-2)^2$ : \periods[69] \stopitemize \stoptext
