Hi, I have two enumerations: \defineenumeration [exercici] [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup},right={\egroup},width=fit,headstyle=\ss] \defineenumeration [exercicivora] [alternative=serried,text={\startcolor[middlecyan]Exercici\stopcolor},stopper={.\space},left={\bgroup\startframedtext[background=screen,frame=off,width=broad]},right={\stopframedtext\egroup},width=fit,headstyle=\ss] I just want to join into one: when I do \startexercici ... \stopexercici ConTeXt do the first, and when I pass \startexercici[vora] ... \stopexercici then do the second. That is, 'vora' as optional argument. How can I achieve that? I use MKIV. Thanks in advance, Xan. PS: Please CCme
