RemNote offers two options for adding superscripts and subscripts to your notes.

Use the direct

**superscript/subscript**format options. You can find these on the**…**menu after selecting some text, or you can press Ctrl+Shift+. and Ctrl+Shift+, respectively (Cmd+Opt+. and Cmd+Opt+, on a Mac).This method is convenient if you have some very simple math or chemical formulas, or are using the superscripts or subscripts for footnotes or other non-mathematical purposes.

Use

**LaTeX equations**. For more complicated math, you'll get much nicer formatting for both your superscripts/subscripts and the rest of your equation by using LaTeX. Type`$$`

to start entering a LaTeX equation.

See Writing Equations with LaTeX for a detailed treatment of this feature.
