Question: How to enable "copy-selection-no-clear" option?

[waldauf]

Hello,

first, thank You for Your great config which I've been using for years.

I would like to have the possibility to copy the text in copy-mode (via keyboard or mouse) and after copying to register/clipboard I stay in copy-mode. I found out there is an option for that called copy-selection-no-clear. But I am not sure how to use it with Your config.

Is it possible to set this behaving in Your config?

• "y" to copy text to TMUX's register.
• "Enter" to copy text to system clipboard

Hello @waldauf 👋

You can add this to your .local customization file:

bind -T copy-mode-vi y send -X copy-selection-no-clear #!important

But after I tested it, even though I set tmux_conf_copy_to_os_clipboard=false, what I copy into tmux buffer is still synced with my OS clipboard and I need to investigate why it's the case with a recent tmux.

Tmux has evolved a lot and according to https://github.com/tmux/tmux/wiki/Clipboard it depends on many factors whether it's going to copy to the OS clipoard.

Hi @gpakosz !
Thank You for Your help. I dived more deeply into it and played with the setting and found this magic configuration which enables me:

• Stay in copy-mode after copy text, including mouse text marking.
• y copies to Tmux register.
• Enter copies to the system clipboard.

Configuration part in .local:

tmux_conf_copy_to_os_clipboard=true

You don't need reattach-to-user-namespace as of tmux 2.6

Now I verified that it doesn't work according to my wish. Everything is also stored in the system clipboard. I hope my future-self will fix it. :D

I have to run on MacOS and there was a problem without reattach-to-user-namespace. Will try it again without.
