There are three ways to use the Stack function: “^”, ”/” and ”#”, we can add one of these symbols before or after the text, then selecting the symbol as well as the text and click the Stack button, we’ll get the superscript, subscript or fractional number effect.

Entering “2^”, then selecting them and click the Stack button will get the squared effect.
