title: TMUX - setting up vi mode
body: <p>I heard much good about TMUX but so far I am just failing with the setup.
  I would like to use the vi mode that allows you to copy with &quot;SPACE&quot; an &quot;ENTER&quot;.
  Currently I must use CTRL+SPACE and ALT+W.</p>
  <p>I am running KALI 5.9.0 and TMUX 3.1c
  When I run TMUX and check the setting it shows me the following:</p>
  <pre><code>$ tmux show -g status-keys
  status-keys emacs
  $ tmux show -g mode-keys  
  mode-keys emacs
  
  </code></pre>
  <p>My ~/.tmux.conf files looks like this:</p>
  <pre><code>set-window-option -g status-keys vi
  set-window-option -g mode-keys vi
  </code></pre>
  <p>I also tried the following two:</p>
  <pre><code>setw -g status-keys vi
  setw -g mode-keys vi
  </code></pre>
  <pre><code>set -g status-keys vi
  set -g mode-keys vi
  </code></pre>
  <p>I killed all tmux session and checked again but it seems as something is permanently overwriting my vi mode.
  What am I missing?</p>
