That might be useful for those depending on it, and presumably there is a \stackscripts, too. Just comes to my mind: Though probably non-standard in typesetting, one might make a slight typographic difference between π₯Β²β and π₯βΒ² by letting the sub- or superscripts that come later partially, but not fully, to the position of the one that comes before. For example, π₯βΒ² might mean the square of π₯β, and π₯Β²β the component 0 of π₯Β², not necessarily the same. Traditionally, such things are left for the reader to interpret. ___________________________________________________________________________________ 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 ___________________________________________________________________________________
