You can optionally add on or off to specify which state you want; otherwise the option is simply toggled. This option is specific to one window, so it won’t change the way your other sessions or windows operate. When you’re done, toggle it off again by repeating the command. source
In addition to these commands, you can also hold down <prefix> and use the arrow keys
:resize-pane -D (Resizes the current pane down)
:resize-pane -U (Resizes the current pane upward)
:resize-pane -L (Resizes the current pane left)
:resize-pane -R (Resizes the current pane right)
:resize-pane -D 20 (Resizes the current pane down by 20 cells)
:resize-pane -U 20 (Resizes the current pane upward by 20 cells)
:resize-pane -L 20 (Resizes the current pane left by 20 cells)
:resize-pane -R 20 (Resizes the current pane right by 20 cells)
:resize-pane -t 2 20 (Resizes the pane with the id of 2 down by 20 cells)
:resize-pane -t -L 20 (Resizes the pane with the id of 2 left by 20 cells)
Pressing <prefix> [ places us in Copy mode. We can then use our movement keys to move our cursor around the screen. By default, the arrow keys work. we set our configuration file to use Vim keys for moving between windows and resizing panes so we wouldn’t have to take our hands off the home row:
setw -g mode-keys vi
With this option set, we can use h, j, k, and l to move around our buffer. You can view the full list of vi bindings for copy mode with:
:list-keys -t vi-copy
