This. With so much of my work being done with Claude Code via terminal, I’ve used vim and tmux more than I have in the 20 years since I was first introduced.

How many people don’t know tmux in the industry is really beyond me.

With all the buzz about orchestrating in the age of CLI agents there doesn't seem to be much talk about vim + tmux with send-keys (a blessing). You can run as many windows and panes doing so many different things across multiple projects.

What's the elevator pitch if I already know Screen and I can just open multiple windows of the terminal emulator?

No pitch - just use screen, most people use tmux in exactly the same way - open a few splits and switch between them with keyboard shortcuts.

Tmux is better supported by other tools, such as fzf.

I switched from screen to tmux due to rumor about the screen code base. Maybe not a good reason. But I don’t regret it, tmux works well.

Just an honest opinion of someone who didn’t have skin in the game. Not sure if it helps.

The people GP are talking about don't know about GNU screen either.

same, although I'm using zellij instead of tmux. Copilot works well in vim too.

Nearly this, but using ghostty instead of tmux. You don’t get the remote connection aspect of tmux, but for splitting/zooming/preserving windows it is fantastic. The best part is you can configure natural shortcuts rather than using a leader for everything.

As a tmux user, sell me on ghostty. I hate the leader key, especially in VIM.
