For that reason I would like to cross out some numbers. Unfortunately overstrike doesn't do the trick, eg with a 4 the overstrike is practically invisible. Is there any way to get a diagonal stroke like the latex module "cancel" can do? Thanks for any suggestions, Martin \starttext \startformula \frac{\overstrike{2}}{\overstrike{4}} = \frac{1}{2} \stopformula \stoptext ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks Henri for pointing to a solution you already offered on stackexchange! I will save it as a good universal solution. Thanks to Kitz, for the very specific solution. This is what I am using at the moment.
