Resizing Panes
You can also resize panes if you don’t like the layout defaults. I personally rarely need to do this, though it’s handy to know how. Here is the basic syntax to resize panes:
12345678910
PREFIX : resize-pane (By default it resizes the current pane down)PREFIX : resize-pane -U (Resizes the current pane upward)PREFIX : resize-pane -L (Resizes the current pane left)PREFIX : resize-pane -R (Resizes the current pane right)PREFIX : resize-pane 20 (Resizes the current pane down by 20 cells)PREFIX : resize-pane -U 20 (Resizes the current pane upward by 20 cells)PREFIX : resize-pane -L 20 (Resizes the current pane left by 20 cells)PREFIX : resize-pane -R 20 (Resizes the current pane right by 20 cells)PREFIX : resize-pane -t 2 20 (Resizes the pane with the id of 2 down by 20 cells)PREFIX : resize-pane -t -L 20 (Resizes the pane with the id of 2 left by 20 cells)
Copy mode:
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. tmux has a vi mode for working with the buffer as well. To enable it, add this line to .tmux.conf:
1
setw -g mode-keys vi
With this option set, we can use h, j, k, and l to move around our buffer.
To see all of the avilable commands in vi mode you can use the following at the tmux command prompt (Ctrl+b :)
1
list-keys -t vi-copy
To get out of Copy mode, we just press the ENTER key. Moving around one character at a time isn’t very efficient. Since we enabled vi mode, we can also use some other visible shortcuts to move around the buffer.
For example, we can use “w” to jump to the next word and “b” to jump back one word. And we can use “f”, followed by any character, to jump to that character on the same line, and “F” to jump backwards on the line.
