Open all links in a new window

Like other editors, when we add a href link, that link should be opened up in another browser window, instead, it leaves our website. Not good at all. Our readers should never leave our website. When I double-click on a text, an option to select target="_blank" or make all links that default. Is there a way to achieve this? I’d modify the core for this as this is very important. Thanks

Absolutely not.
