I still don't get buffers

they have no use for copy buffers, they are still configuring emacs.

No, but I'm happy to talk to you about our lord and savior nano

Obligatory boo and/or hiss

I've also been meaning to give emacs a try but haven't found the time or energy to figure out how to exit vim

I'm just an emacs ... enjoyer (...?) and I just don't understand the post. I'm pretty sure buffers here refer to something different from emacs buffers as they're completely unrelated to clipboards. Then from a quick scan of the plug-in mentioned it seems to mimic the clipboard ring emacs has had for many decades (always?).

Basically I have no idea what's going on here.

I had to learn emacs for my engineering computation class, up to the point that we were required to present our code in emacs if we had questions to ask during office hours.

I got quite used to it by the end of that course.

We be rocking that kill ring !

What would an operating system need yank registers for? Maybe if you get a good text editor to go with it, like Evil Mode 😉
