Select Pane with C-<number> in tmux

Question

In tmux, the default behavior for processing C-b 0 is to jump to window 0. I would like C-b C-0 to jump to pane 0 in the current window. My attempts at adding,

bind-key C-0 select-pane -t 0 

to my .tmux.conf have failed. Is there something else I'm missing?

Answer 1

Not exactly the way you are looking for, but I doubt you have a reason not to love the following:

1. display-panes or the likes (<prefix> + q by default),
2. enter the number of the pane you are switching to.

Answer 2

You need to modify your terminal so that tmux can recognise control+digit keystrokes correctly. (source: https://unix.stackexchange.com/questions/96884/using-ctrl0-9-to-cycle-between-windows-using-tmux)

If you are using iTerm2, for example, then:

1. go to Preferences > Profiles > Keys and click +
2. input ctrl+0 as the keyboard shortcut
3. select Send Escape Sequence from the action drop-down menu
4. input Esc+[27;5;48~ in the characters to send textbox
5. click OK, then restart iTerm

Then, finally add to your .tmux.conf the following:

bind-key C-0 select-pane -t 0 

restart tmux (make sure to close all sessions withtmux kill-session). You should now be able to select pane number 0. To get the other 9 keys to work, repeat the above 5 steps with the appropriate escape sequences. They can be found in the link provided.
