<title>Superscript and Subscript</title>
<p>
Some equations may require numbers to be entered in superscript or subscript form. e.g.
</p>
<example>
<p>
<math xmlns="http://www.w3.org/1998/Math/MathML" alttext="x³+2x²−5">
<mrow>
<msup>
<mi>x</mi>
<mn>3</mn>
</msup>
<mo>+</mo>
<mrow>
<mn>2</mn>
<msup>
<mi>x</mi>
<mn>2</mn>
</msup>
</mrow>
<mo>-</mo>
<mn>5</mn>
</mrow>
</math>
</p>
</example>
<p>
To enter superscript numbers with the mouse select the number mode using the <gui>↑n</gui> and <gui>↓n</gui> buttons.
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 button.
</p>
<p>
To enter superscript numbers with the keyboard hold down <key>Ctrl</key> while entering the number.
Hold <key>Alt</key> for subscript.
</p>
<p>
The number mode returns to normal when entering the next non-number character (e.g. +).
