I saw you created a macro to illustrate the use of subscript and superscript with TLatex
I think it could be a good idea to add examples to illustrate the use of sub/superscript “before” the "x"
For example
_{2}x^{2y}
^{3}x^{2y}
{}^{3}_{2y}x^{2y}
Especially, I remember I lost few time to understand that I have to add “{}” if I want to display a subscript and a superscript before the “x”
