// Configuration (to be set from [[Special:MyPage/common.js]]):
//   window.charinsertCustom – Object. Merged into the default charinsert list. For example, setting
//       this to { Symbols: '‽' } will add the interrobang to the end of the Symbols section.
//   window.editToolsRecall – Boolean. Set true to create a recall switch.
//   window.charinsertDontMove – Boolean. Set true to leave the box in its default position, rather
//       than moving it above the edit summary.
//   window.updateEditTools() – Function. Call after updating window.charinsertCustom to regenerate the
//       EditTools window.
