This should be easy enough to do, but I'm just not getting it. All I want is my page's 301 redirect through a custom field to open in a new browser tab, but I cannot figure out where to add the target="_blank".
I do NOT want to use a plugin just for this. That would be silly.
(If you suggest adding code, please tell me what file to add it to. I.e. - functions.php, etc., and the line as it should be typed. I'm not a php genius, obviously.)
