Moving panes between tmux sessions is something that makes tmux a very flexible and powerful tool. I don't need this feature very often, but it comes in clutch when you need it.

Pull a pane from any other session #

Using choose-window I was able to come up with a way to select any pane withing any other session and join it into my current session.


# Choose a pane to join in horizontally
bind f choose-window -Z 'join-pane -h -s "%%"'

Push/Pull from scratch #

I've long had this one in my tmux config, I always have a "scratch" session that I'm running, I often use for looking at things like k9s accross repos within a popup.

This use case puts a pane into the scratch session, then pulls it back out. I will use this to move a pane between sessions in the rare cases I need to do this.


# push the active pane into the scratch session horizonally
bind -n M-f join-pane -ht scratch
# pull the last active pane from the scratch session horizonally into this session
bind -n M-F join-pane -hs scratch
