This screen is accessed from the back-end Joomla! administrator panel. It is used to add or edit redirects.
Navigate to the the Redirect Manager. To add a new Redirect, click on the New icon in the toolbar. To edit an existing Redirect, click on the Redirect's Expired URL field or check the Redirect's checkbox and press the Edit icon in the toolbar.
This is where you can add a new redirect or edit an existing one. The URL you want to redirect from must not be a working one on your website which actually loads a web page. It can be the URL to a web page which you have disabled in the Joomla! back-end administrator interface. The Source URL you specify when you create the redirect should be the full URL as you would type it in your web browser. The Destination URL you specify when you create a redirect must be the full URL as well.
At the top right you will see the toolbar.
