In High School, they taught us to use arrows above to indicate vectors, but
most people (including me) simplified 'em to macrons. At Uni, most teachers
use macrons - the rest doesn't bother to differentiate vectors from scalars.

Neat. I've not seen any way to indicate that here, but then I've not done
anything much involving tensors yet.

PS You didn't answer my question about f^III vs f''' - you'd really write them
differently? Since I first saw f^IV I've been sort of assuming that f' is, in
origin at least, an f with a superscript Roman numeral one.
