Thanks Hans for the reply. I take to type some formulas larger font, so that's why I opted to frame their own definition of a formula environment with small print. Switch entire mathematical text on small I don't want. Therefore, I would like to have both:

\startformula .... \stopformula

and

\startsmallformula .... \stopsmallformula

\startformula has a optional argument which let you change the font, e.g. \startformula[9pt]. \definestartstop[smallformula] [before={\startformula[small]}, after=\stopformula] \starttext \startformula c^2 = a^2 + b^2 \stopformula \startformula[small] c^2 = a^2 + b^2 \stopformula \startsmallformula c^2 = a^2 + b^2 \stopsmallformula \stoptext Wolfgang

Hello Wolfgang. After some searching and experimenting, here is my functional solution. I wrote it into the wiki. I have not found there eg. defineformula command etc Jaroslav Hajtmar \defineformula[MY][ align=left, strut=no, spacebefore=, spaceafter=, ] % so you can modify the settings of defineforumla[MY] \setupformulae[MY][align=right,strut=yes,spacebefore=medium,spaceafter=big] % so we can create new start-stopsmallformula \definestartstop[smallformula] [before={\startformula[small]}, after=\stopformula, ] % and we can so create new start-stopmysmallformula: \definestartstop[mysmallformula] [before={\startMYformula[small]}, after=\stopMYformula, ] % and here is my shortcuts: \let\bmyformula\startmysmallformula \let\emyformula\stopmysmallformula \starttext \title{Example of use and behavior} startformula: \startformula c^2 = a^2 + b^2 \stopformula startformula$[$small$]$: \startformula[small] c^2 = a^2 + b^2 \stopformula startformula[8pt]: \startformula[8pt] c^2 = a^2 + b^2 \stopformula startsmallformula: \startsmallformula c^2 = a^2 + b^2 \stopsmallformula startmysmallformula: \startmysmallformula c^2 = a^2 + b^2 \stopmysmallformula startMYformula: \startMYformula c^2 = a^2 + b^2 \stopMYformula startMYformula[5pt]: \startMYformula[5pt] c^2 = a^2 + b^2 \stopMYformula bmyformula: \bmyformula c^2 = a^2 + b^2 \emyformula \stoptext http://wiki.contextgarden.net/defineformula Dne 11.3.2015 v 18:18 Jaroslav Hajtmar napsal(a):

Thanx Wolfgang for reply. I had no idea that it is possible in this way to change the font size. I could not figure a way for your solution set alignment formulas to right and how work \defineformula and \definestartstop together.

After defining a new MY formula in combination with your solution works it fine, as I had imagined. Is there any possibility of setting of parameters a newly defined formulas? Or, it can not be done, and everything must be solved within the initial definition?

One more thanx Jaroslav Hajtmar

\defineformula[MY][ align=right, strut=yes, spacebefore=, spaceafter=, ]

\definestartstop[smallformula] [before={\startformula[small]}, after=\stopformula, ]
