Today I finally learnt how to move a pane between windows in Tmux and yes - I will share this vodoo knowledge with you guys.

Searching through the internet gives us this:

# pane movement
bind-key j command-prompt -p "join pane from:"  "join-pane -s '%%'"
bind-key s command-prompt -p "send pane to:"  "join-pane -t '%%'"

This is the most popular binding for this 'moving' purposes. But - when you try it entering window number as the destination (or source) you get a message:

Can’t join a pane to its own window

WTF?

Let's RTFM:

 join-pane [-bdhv] [-l size | -p percentage] [-s src-pane] [-t dst-pane]
       (alias: joinp)
      Like split-window, but instead of splitting
      dst-pane and creating a new pane, split it and
      move src-pane into the space.  This can be used
      to reverse break-pane.

Yes - so this gives us nothing.

So - lurking through the horizon of the internet I found this:

So it looks like the full path takes 2 arguments: window_number.pane_number

So yes - bindings are still valid but instead entering single window number we should enter exact location like 1.3 (assuming you got at least 2 panes in 1 window)

Yes - this was not that obvious
