How do you get a superscripted note reference mark?

To create a superscripted note reference mark, you can typically use keyboard shortcuts or formatting options in your Word processor. For example, in Microsoft Word, you can type the number or symbol and then highlight it, then press "Ctrl + Shift + =" to superscript it. Alternatively, you can use the "Font" dialog box to select the superscript option. In HTML, you can use the <sup> tag to achieve the same effect.
