All,

We have:

\placeformula[eq:commonb] \startformula (1)^2+(\sqrt{4x+13})^2=(2x)^2, \stopformula

This gives us a centered equation with an number pushed to the right edge of the page (I probably should say text area).

What we'd like to do, just in this one example (not globally), is add a little "smiley face" icon on the same line as the displayed equation and equation number, but pushed to the left edge of the page (I probably should say text area).

Possible?

It should be possible to do this using a special version of \startalign, but I cannot figure it out. Maybe Aditya can help?

Here is one solution. Explaination inline. % I do not know what you want for a smiley, so I use square instead \def\smiley{\square} \starttext This is the basic idea. Have an alignment structure with three blocks, each block of 1 column, put the simley in the first block, the equation in the second block, and keep the third block empty. The trick here is to have {\em 1 fil} in the distance. \definemathalignment[dosmiley] [n=1,m=3,distance=3em plus 1 fil] \placeformula[+] \startformula \startdosmiley \NC \smiley \NC (1)^2 + (\sqrt{4x+13})^2 = (2x)^2 \NC \NR[+] \stopdosmiley \stopformula Ah, it works. So we can add some syntax sugar around this, so that the formula is easier to key in. \def\startsmileyformula% {\startformula \startdosmiley \NC \smiley \NC} \def\stopsmileyformula% {\NC \NR[+] \stopdosmiley \stopformula} \placeformula[+] \startsmileyformula (1)^2 + (\sqrt{4x+13})^2 = (2x)^2 \stopsmileyformula If you only want a smiley without the equation, it also works. :-) \startsmileyformula (1)^2 + (\sqrt{4x+13})^2 = (2x)^2 \stopsmileyformula \stoptext Can you send me how you make a smiley. I will then put the code in myway on alignment. Aditya
