Hi, I use luatex 0.43 with yesterday's beta. Running \everymath = {\displaystyle} \starttext ${a\over b}$ \stoptext results in ! Use of \dospecialabout doesn't match its definition. l.4 ${a\over b }$ Plain format under luatex has no problem here. If I change \over to \times it runs with fonts changed to roman (i.e, not math italics). Thank you. Eythan

taco and i looked into it (fearing big problems) but it's actually normal; use \everymath = \expandafter{\the\everymath \displaystyle} or \appendtoks \displaystyle \to \everymath as (among other important things) \everymath does initialize \over ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

And with \frac it can be configured at context low level (why no key for \setupmathematics?) \chardef\mathfracmode=1 % 0=auto, 1=displaystyle, 2=textstyle, 3=scriptstyle, 4=scriptscriptstyle, 5=mathstyle $\frac{a}{b}$ Wolfgang

$\frac{a}{b}$
I am thinking of incoprorating a "nath like" frac in ConTeXt. So, we can have \definemathfraction[frac][style=...] where style can take values default: the current frac implementation auto: the nath like implementation displaystyle: the current dfrac implementation textstyle: the current tfrac implementation scriptstyle/scriptscriptstyle: (not sure when they would be needed) I need to check what is the difference between mathfracmode=0 and 5. We can also interface to vulgar fractions. Aditya
