In a tmux session, I'm running vim in one pane and a terminal in another pane.
Recently, I figured out how to enter visual mode in tmux but it doesn't help much now.

Can I yank selected text from a pane and paste it to another (within vim or not), and how can I do this?
The other way, how can I yank some text from vim and paste it to another pane?

  • I could have sworn Ive answered something like this before, but I can’t find it. The answer is yes, there are tmux bindings that allow this (and tpope has a plugin, tbone I think, that makes it easy in vim). But if your question is about tmux and not vim, it’s off-topic here.

Plugin vim-tmux-clipboard seems to be what you're after. It mirrors Vim's unnamed register (default one for yank, delete and put operations) to and from the tmux clipboard.

Make sure you take a close look at the requirements when enabling this plug-in. For Vim, you need at least version 8.0.1394 and you also need plug-in vim-tmux-focus-events to be enabled. (For NeoVim, there are no additional requirements.)

You also need to enable set -g focus-events on on tmux for it to work.

I am not sure how to paste to terminal, but you can make the two vim instances share the same clipboard. First check that if your vim supports clipboard by typing vim --version, if you see +clipboard in the output, then in your ~/.vimrc, add

set clipboard=unnamed

now you can freely yank and paste between tmux panes and windows.

  • Note that this also means copying text in other applications changes what will be put by default

  • @D.BenKnoble Thanks for reminding, that is a little bit tricky...
