^ runs the command TeX-insert-sub-or-superscript (found in LaTeX-mode-map),
which is an interactive compiled Lisp function in ‘tex.el’.

It is bound to _, ^.

(TeX-insert-sub-or-superscript ARG)

Insert typed key ARG times and possibly a pair of braces.
Brace insertion is only done if point is in a math construct and
‘TeX-electric-sub-and-superscript’ has a non-nil value.
