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.
