Absolutely! You also have full control over the history size, along with powerful search capabilities. You can move panes and windows seamlessly across sessions, and even share those sessions with other users. My yank script integrates with tmux buffers, so copy/paste works flawlessly, even in vertical splits. I strongly disagree with the article; I simply can’t imagine using a terminal without tmux.

screen does as well. Unless I'm missing something here.

Loosely speaking neovim is a terminal multiplexer, and it can also do this, you have full vim motions and commands available on terminal buffers.

Do you mean select into the clipboard?

To tmux's clipboard and if required to the system clipboard too...

set -s copy-command 'xsel -i'
