The contents of \hpos are set as text, even when \hpos is in mathematics, so I wrote an \mpos macro that uses \hpos but sets the contents as display-style math. This isn’t great for spacing, and it does't adapt to different math styles. \framed has a math version, \mframed, that sets the contents in the appropriate math style. If anyone know a way to accomplish that with \hpos, I’d love to know.

I tried using \mathboxanchored, and was able to get the bottom two equations shown here. (The top equation uses \hpos, for comparison.)

There are two problems that I didn’t know how to fix.
1) The line connects to the box including the subscript or superscript, not just to the e.
2) I cannot make multiple connections to a single object, like the e^\mu in the center. If I try to connect top and bottom, I get no connections anywhere in the entire document.
The code for the formulas is:
\startformula
% Each \connectboxanchors works alone, but both together make trouble:
\connectboxanchors[top][top]{X}{Y}
%\connectboxanchors[bottom][bottom]{Y}{Z}
\mathboxanchored{X}{e}_\alpha \mathboxanchored{Y}{e}^\mu \mathboxanchored{Z}{e}_{\dot\beta}
= \textfrac{1}{\sqrt{2}}\sigma_{\alpha\dot\beta}^\mu
\stopformula
I added code to turn the arrow produced by \connectboxanchors into my contraction overlay, but that doesn’t affect these issues.
> in your example we need a way to anchor on just the 'e' right? or do you want it on the e + super/subscript?
Yes, we only need to anchor to e.
Thanks!
Gavin
