If you want to click on some DOM on search, go to the console in the inspect element and look for the particular command. The code in wizzyCustom.js may look something like this.
window.onWizzyLoaded.push(function () { window.wizzyConfig.events.registerEvent( window.wizzyConfig.events.allowedEvents.BEFORE_INIT, function (payload) { payload.common.lazyDOMConfig.identifiersToClickOnSearch.push("#icon-search") return payload; } ); ); });
