If you're working locally I can't think of much. OSC52 works to copy to your local clipboard from a remote system (e.g., over ssh) from within tmux or nvim as long as you are using a terminal that supports it.

I use it to copy from remote system when I'm in nvim (`"+y`).

Here are a couple links that relate to tmux and nvim.

- tmux: https://github.com/tmux/tmux/wiki/Clipboard

- nvim: https://neovim.io/doc/user/provider.html#clipboard-osc52

The benefits it works everywhere, even on the blink app on iPhone when you suddenly have to pull out your phone in an emergency, connect to your tmux session away from your usual workstation.
