1. my screenshot is possibly dependent on the font, DejaVu Sans Mono


2. by the way with foo_{bar},  having the _ at the main baseline and the
{bar} with its top at the level of the _, which perhaps is not the
thing one would do a priori, looks like a good option to me. Better
than moving deep down the _ so that it looks like _{bar}, and better
(to me) than having as in my screenshot the _{bar} look like -{bar}

is there a way I can configure the Tassilo's variables so that it looks like


A_
  B_
    C

sort of ? (with smaller typefaces)

Best,
