   Format: MarkdownItexCan someone tell me how you make a subscript appear to the left of an expression? For example, instead of $R$ appearing to the right as in $Mod_R$, make it appear to the left of $Mod$ as a subscript?

   Format: MarkdownItexYeah, I think that's the best there is. I used to use that hack in ordinary LaTeX too, until i discovered the `\prescript` command in the `mathtools` package; but I don't think iTeX has a `\prescript`.

   Format: MarkdownItexiTeX does provide [`\multiscripts`](https://golem.ph.utexas.edu/~distler/WebTeX/docs/wtxsec5.html#SUPER). Is this being eschewed as non standard? $$\multiscripts{_0^2_1}{R}{_i^j_k} \quad \quad \multiscripts{_R}{Mod}{} \quad or \quad \multiscripts{_R} Mod {}$$
