Clover: the right-click menus' Theme, the Format menu's and palette's Customize
Theme and the Styles gallery's Customize all open the same dialog, so they and
the dialog share one name, and the Styles button's Aa icon; scoped, the dialog
reads Customize Font Styles for This Section. In the gallery it sits under a
rule, where OneNote 2010 keeps Clear Formatting, and in context menus it comes
last, under a rule. A gallery group can start under a rule, which More Symbols
gains too.
