There is this code in Magento 2 in
Magento\Catalog\Controller\Adminhtml\Product\Save.php
if ($redirectBack === 'new')
{
$resultRedirect->setPath('catalog/*/new'
,['set' => $productAttributeSetId
,'type' => $productTypeId]);
Can anyone tell me what does 'catalog/*/new' refers to? I have checked the controller folder and haven't found new.php file anywhere.
