appear if you click on its label.)</p>

in the “Math Settings” submenu of the MathJax contextual menu.
It allows the user to change between the <cite>HTML-CSS</cite>, <cite>NativeMML</cite>,

This submenu lets the user select what font to use in the
mathematics produced by the <cite>HTML-CSS</cite> output processor.  Note that
changing the selection in the font menu will cause the page to

submenu lets the user select what events should be passed on to
the <a class="reference external" href="http://www.dessci.com/en/products/mathplayer/">MathPlayer plugin</a>, when it is
present.  Mouse events can be passed on (so that clicks will be
processed by MathPlayer rather than MathJax), and menu events can
be passed on (to allow the user access to the MathPlayer menu).
