Scripts

The standard script templates are:

• Subscript
• Superscript
• Subscript and Superscript
• Multiscripts
• Underscript
• Overscript
• Underscript and Overscript

These are all self-explanatory, except for one subtlety concerning under- and overscripts. In MathML, limits are attached to summation and product signs using the under and overscript template. However, it is customary in mathematical typesetting to place the limits for summations and products in the sub and superscript positions when an equation appears inline with other text to conserve vertical space. Thus, when the display style is inline, the under and overscript templates render just like the sub and superscript templates in certain cases. You can manually override this behavior by setting properties on the under and overscript templates.

Choosing the Multiscripts entry opens a dialog box, where you can enter the number of pre- and post-scripts you want. Values of 0 are acceptable (in case you don't want any pre-script, or any post-script.) Note that, per MathML specifications, the subscripts and superscripts should always come in pairs. If you don't want one of them, you would have to enter a space in the corresponding slot.
