    <p>
    Some equations may require numbers to be entered in superscript or subscript form, such as:
    </p>
    <example>
    <p>x³+2x²−5</p>
    </example>
    <p>
    To enter superscript numbers with the mouse select the number mode using the <gui>↑n</gui> and <gui>↓n</gui> buttons (available in the <gui>Advanced Mode</gui> and the <gui>Programming Mode</gui>).
    When one of these modes is active clicking the number buttons will enter numbers in superscript or subscript.
    To return to normal number mode click the active number button.
    </p>
    <p>
    To enter superscript numbers use <keyseq><key>Ctrl</key>number</keyseq>, for subscript numbers use <keyseq><key>Alt</key>number</keyseq>. 
    </p>
    <p>
    The number mode returns to normal when entering the next non-number character, such as "+" or "-".
    </p>
