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.

I have tmux-thumbs, but only been able to use it a few times. Apparently most of what I need to copy is not ip's and URLs. But this tmux-yank looks like what I'm looking for. I'll give it a try. Thanks.
