There are no built-in shortcuts for these. You could write your own UDF, but
this won't work in edit mode on a cell.
Maybe John Walkenbach's SuperSub add-in would be what you want.

Allows selecting text to Super or Sub.

We all know there are built-in shortcut keys for Font.underline
[CTRL+u], .italic [CTRL+i], .bold [CTRL+b]and corresponding toolbar
buttons in Excel.
They are toggling shortcut keys which even work during typing/editing
in a cell, which is very convenient.
I've been struggling to make such shortcut keys for superscript and
subscript, without success.
Would anyone kindly tell me how?
I am currently trying to learn EXCEL 2000 VBA and ACCESS 2000 VBA.
