FAQ

Q1: Can superscript and subscript be used at the same time?

They cannot be used at the same time. A piece of text can only be set to either superscript or subscript, not both simultaneously.

Q2: What are common scenarios for using superscript and subscript?

Superscript is often used for mathematical exponentiation (e.g., X²) and footnote markers; subscript is often used for chemical formulas (e.g., H₂O) and mathematical variable indices.

Notes

  • The superscript/subscript effect only applies to the currently selected text
  • After setting superscript/subscript, the text size will automatically shrink
  • Text in scanned PDFs may not be directly editable and requires OCR recognition first
