TMUX CHEATSHEET

So ~/.tmux.conf overrides default key bindings for many action, to make them more reasonable, easy to recall and comfortable to type.

tmux key	Description
C-a	Default prefix, used instead of "C-b". Same prefix is used in screen program, and it's easy to type. The only drawback of "C-a" is that underlying shell does not receive the keystroke to move to the beginning of the line.
<prefix> C-e	Open ~/.tmux.conf file in your $EDITOR
<prefix> C-r	Reload tmux configuration from ~/.tmux.conf file
<prefix> r	Rename current window
<prefix> R	Rename current session
<prefix> _	Split new pane horizontally
<prefix> |	Split new pane vertically
<prefix> <	Select next pane
<prefix> >	Select previous pane
<prefix> ←	Select pane on the left
<prefix> →	Select pane on the right
<prefix> ↑	Select pane on the top
<prefix> ↓	Select pane on the bottom
<prefix> C-←	Resize pane to the left
<prefix> C-→	Resize pane to the right
<prefix> C-↑	Resize pane to the top

<prefix> <	Move to previous window
<prefix> Tab	Switch to most recently used window
<prefix> L	Link window from another session by entering target session and window reference
<prefix> \	Swap panes back and forth with 1st pane. When in main-horizontal or main-vertical layout, the main panel is always at index 1. This keybinding let you swap secondary pane with main one, and do the opposite.

<prefix> +	Toggle zoom for current pane
<prefix> x	Kill current pane
<prefix> X	Kill current window

<prefix> D	Detach other clients except current one from session
<prefix> C-s	Toggle status bar visibility
<prefix> m	Monitor current window for activity
<prefix> M	Monitor current window for silence by entering silence period
