In emacs, you split a window with C-x 2 (one above the other) or C-x 3 (one next to the other).

How can I get the same key bindings in tmux?

Also, once a window is split, in emacs you cycle through them with C-x o. Can I configure tmux to use the same key?

  • Have you read the man page for tmux? It should be obvious what to do. Unfortunately if you do it, then C-x stops working as a prefix key in Emacs because tmux will interpret it instead. – Kyle Jones Nov 7 '13 at 23:42
  • It would be nice if there were a tmux command I could use to disable those keys just for the one window in which I run emacs. Alternatively, I'd be happy to use C-b C-x 2 instead of the normal C-x 2 to split windows. – Frank Nov 8 '13 at 23:42

Have a look at the must read at http://pragprog.com/book/bhtmux/tmux; you'll get anything you need Further on, try out this:


# Setting the prefix from C-b to C-d 
# START:prefix
set -g prefix C-d 
# END:prefix 

# Ensure that we can send Ctrl-A to other apps 
bind C-d send-prefix 

# Free the original Ctrl-b prefix keybinding unbind C-b
unbind C-b

bind | split-window -h
bind _ split-window -v

And this for moving between panes:

bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

Both from the previous reference and the man page.

  • Much better now, thanks @Jason, I'll do my best next time. – csantosb Nov 23 '13 at 21:58
  • Sorry, I don't understand how this answers my questions and would give me C-x 2 and C-x 3 for splitting? – Frank Nov 24 '13 at 6:16
  • Put this code in your config file along with whatever you need – csantosb Nov 25 '13 at 16:23

    @csantosb - I don't think those keys are what @frank is looking for. Emacs splits with Ctrl-x 2, and switches with Ctrl-x o. – Ken Williams Aug 10 '15 at 21:52
