浏览器应用集成嵌入WPS是否支持鼠标键盘事件监听？

请问一下wps嵌入到浏览器中除了下面的几类事件，还有其他的事件吗？或者说可以给鼠标右键菜单添加东西吗？ pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "DocumentBeforeNew", "DocumentBeforeNewCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "NewDocument", "NewDocumentCallBack"); pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "DocumentBeforeOpen", "DocumentBeforeOpenCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "DocumentOpen", "DocumentOpenCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "DocumentBeforeSave", "DocumentSaveAndSaveAsCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "DocumentBeforePrint", "DocumentBeforePrintCallBack"); pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "DocumentViewFocusIn", "DocumentViewFocusInCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "DocumentBeforeClose", "DocumentBeforeCloseCallBack"); pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "DocumentAfterSave", "DocumentSaveAsOrSaveDoneCallBack"); pluginObj.registerEvent("DIID_ApplicationEvents4", "ProtectedViewWindowActivate", "DocumentAfterCloseCallBack"); pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "DocumentViewFocusOut", "DocumentViewFocusOutCallBack"); pluginObj.ApplicationEx.registerEvent("DIID_WpsApplicationEventsEx", "ContentChange", "DocumentContentChangeCallBack");
