Here is my .tmux.conf
set-option -g prefix C-\
bind-key C-p select-pane -U
bind-key C-n select-pane -D
bind-key C-b select-pane -L
bind-key C-f select-pane -R
What I want is to bind C-\ C-b to switch to the left pane, C-\ C-f to switch to the right pane and etc.
But I got the message .tmux.conf:2: usage: set-option [-agosquw] [-t target-session|target-window] option [value] when I started tmux.
Any idea how to do it?
It has to do with your choice of prefix being C-\. The '\' character is used to indicate that the next line is a continuation of the set-option command. Add a gap after C-\ or quote C-\ as explained here: https://superuser.com/questions/417236/tmux-with-non-alphanumeric-prefix
You can use the following:
set-option -g prefix 'C-\'
bind-key C-p select-pane -U
bind-key C-n select-pane -D
bind-key C-b select-pane -L
bind-key C-f select-pane -R

The version I am running is tmux 3.3a
I cannot copy text to my clipboard when i scroll up in a terminal session. This seems to be because the text i'm highlightning is yellow in color rather than clear. I cannot scroll up in my tmux history and copy text to my clipboard with fn + cmd+c.
If I do not scroll the tmux session, copying to my clipboard works correctly when i press fn + cmd+c.
Here is an image that shows text that I cannot copy to my clipboard with fn + cmd+c.

I have the following minimal tmux config:
unbind C-b
set-option -g prefix C-a
bind C-a send-prefix
set -g history-limit 5000
setw -g mouse on
setw -g monitor-activity on
bind -n C-Left split-window -h
But pressing Ctrl+Left does not do anything. I also tried bind -n C-Left split-window -h but Ctrl+b Ctrl+Left did also nothing.
Isn't is possible to remap Ctrl?
I have following configuration in my tmux config file:
unbind C-b
set -g prefix C-s
bind-key - split-window -v
bind-key \ split-window -h
When I am in tmux, if I try
Ctrl+s : split-window -v
it works. If I try
Ctrl+s -
it does not work. It says No Buffer, and tmux does not do anything.
Any help on how can I debug this behaviour?
The - key is already bound to the delete-buffer command. You can check this by executing tmux list-keys. You must unbind it and then apply your binding:
unbind -
bind-key - split-window -v
I switch panes often and when I press ctrl-a-right I move the the right. Then if I start typing "vim", the 'v' causes a ctrl-a-v (split vertically) to be issued, but I don't want this. How do I make tmux realize this?
In your .tmux.conf, add
bind Up select-pane -U
bind Down select-pane -D
bind Left select-pane -L
bind Right select-pane -R
or if you're using vim directions,
bind k select-pane -U
bind j select-pane -D
bind h select-pane -L
bind l select-pane -R
as detailed in this post: https://superuser.com/a/1273727
My solution was to remove -r in .tmux.conf on the split-window options. Removing -r causes repeats to be disabled.
from
bind -r v split-window -h -c "#{pane_current_path}"
to
bind v split-window -h -c "#{pane_current_path}"
I have been using tmux in iTerm2 for a while now but I have not been using the tmux integration that now comes with iTerm2.
I started looking at using the tmux intergration as it allows you to use the shell intergration inside tmux.
The problem i am encountering is that after i do tmux -CC none of the key bindings inside my .tmux.conf work... I cant even get any of the defaults to work. I would really like to use tmux integration but cant unless i can get the key bindings in my .tmux.conf to work.
Some of the bindings that are not working are;
Rebound the prefix key to C-s
bind-key \ split-window -v -c '#{pane_current_path}'
bind-key - split-window -h -c '#{pane_current_path}'
These are just a couple of examples but basically nothing seems to be working...
My .tmux.conf is
# improve colors
set-option -g default-terminal "screen-256color"
# set base Prefix key to ctrl-s
unbind C-b
set -g prefix C-s
bind-key -r C-s send-prefix
# reload the source config
bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded"

Copying my answer at https://stackoverflow.com/a/47171067/4200039 over:
Someone reported a similar bug at iTerm2 Tmux Integration Default Keybindings not working in 2015. The response from the developer George Nachman suggests that keybindings are not supported:
One of the main goals of the tmux integration is that you use iTerm2's
keystrokes, not tmux's. If there's a specific workflow that you can't
accomplish natively, let me know--there is a lot of power in the
ability to remap keys in iTerm2.
This should be flagged as a duplicate of iTerm 2 not honoring key bindings declared in .tmux.conf but I can't flag it until it has an accepted or upvoted answer.
