This policy lets you configure the Super Drag Drop feature in Microsoft Edge. With this feature, users can drag a link or text from a webpage and drop it onto the same page. They can then either open the URL in a new tab or search the text using the default search engine. If you enable or don't configure this policy, you can use the Super Drag Drop feature on Microsoft Edge. If you disable this policy, you can't use the Super Drag Drop feature in Microsoft Edge.
