I think that I want to do the same as you.
When I post a link in one of my articles, it will default to this …
<a href="https://xxx.com">xxxx</a>
where I want it to default to this…
<a href="https://xxx.com" target="_blank">xxxx</a>
I tried to dig around in the “quicktags.js” file, but so far, no success. I am sure that I AM in the right place though.
Help?
