Pretty sure most of you already know this but for those who don’t: you have two clipboards in Linux. One is the traditional clipboard where you copy with control c and paste with control v. The other one is when you highlight text and use the mouse middle click to paste text.
More details here.
And then there is the “clipboard” (copy paste function) in the nano text editor being a third
You can also configure vim to use the first clipboard (works with nvim but never tested on vim).
