The j is the same size as the i, because its font size is (somehow) determined as if it were attached to the x. My fix was to make '_' be an infix operator that's right associative. That makes $x_i_j$ parse just like $x_{i_j}$, and like how LaTeX appears to behave. > How about a short one :-) I think one of the most important > enhancements will be to support embedded mathtext expressions, eg > > r'some text $\sigma=1$ some more text' > > Currently we have to do something like > > r'$\rm{some text\ }\sigma=1\rm{\ some more text}$' > > which is pretty bad. I'll add that to the list.
