Popup terminal with tmux

.tmux.conf

# ... your other config

bind-key -n M-3 run-shell 'toggle-tmux-popup'
# you can switch `M-3` to any keybindings you like.

toggle-tmux-popup

#!/bin/bash
# 👻 put this file into your $PATH, normally `~/.local/bin/toggle-tmux-popup`
# 👻 this script should have runable permission.

if [ "$(tmux display-message -p -F "#{session_name}")" = "popup" ];then
    tmux detach-client
else
    tmux popup -d '#{pane_current_path}' -xC -yC -w80% -h75% -E "tmux attach -t popup || tmux new -s popup"
fi

@gogongxt It works fine on my machine. I have the following in my .tmux.conf:

# Be more like Vim in copy-mode-vi
bind-key -T copy-mode-vi y send-keys -X copy-pipe 'xclip -i -selection clipboard'
bind-key -T copy-mode-vi Y send-keys -X copy-pipe-end-of-line 'xclip -i -selection clipboard'
bind-key -T copy-mode-vi v if-shell -F '#{selection_active}' { send-keys -X clear-selection } { send-keys -X begin-selection }
