Help:RichText editor - Subscript and superscript

Subscript and superscript formatting is often used in mathematical expressions or footnote references. CKEditor makes it easy to format the text as subscript or superscript with appropriate toolbar buttons.

Subscript

Subscript is a character that is slightly smaller than the text that surrounds it and is set below the baseline. It is often used in mathematical expressions to denote a variable version or the denominator part of a fraction.

To use subscript in your document, press the Subscript toolbar button. To remove the formatting, press the button again.
