Hi dear list! I have a question about the use of delimiters. There are commands as \left ... \right which allow delimiters of variable size, but they are usually asymmetrical. AFAIK, ConTeXt has mechanisms of the form \definemathfence[something][something][command=yes]. My question is: is it possible to make math fences work in a math alignment, e.g. \definemathfence[something][brace][command=yes] \startformula \startmathalignment[n=2,align={middle,middle}] %This won't work (I didn't expected to work, anyway) \NC \NC \something{\frac{1}{2} + \NR \NC \NC x} \NR \stopmathalignment \stopformula so that the fences are the same size? Thank you in advance. Stay safe. Jairo <3
