e-Clubhouse Editing Toolbar - Superscript & Subscript

The Superscript & Subscript buttons decorate the selected text, by setting them in a smaller font, and raising the text up for Superscript, or lowering the text for Subscript.  This should be used sparingly, and not for an entire line of text.

This is commonly used for mathematical functions, such as X₂ or X².
