Keeping external link in same window showing my website

Hi I’m very new to wordpress and trying to make the hyperlinks I put in my news section open within our website, not in a new window but in the same window where you can still see our website at the top of the screen with our logo and menus showing while looking at the new link. I don’t want to divert the traffic to the external link every time and them have to click the back button to get back on our website. Do I need a certain plugin or a special code for this?
Thanks in advance!
