+
+    <p>
+    Some equations may require numbers to be entered in superscript or subscript form. e.g.
+    </p>
+    <example>
+    <p>
+    x³+2x²−5
+    </p>
+    </example>
+    <p>
+    To enter superscript numbers with the mouse select the number mode using the 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. +).
+    </p>
