Useful Commands

Entering the <prefix> gets you into the command mode, then

:new-window -a		# insert new window right next to current
:swap-window -t [pos]	# move curr window


Customizing <prefix>

If you wish to change the prefix from Ctrl + b to something like Ctrl + a, which some people prefer, you could create a file ~/.tmux.conf with the following:

# Remap tmux Prefix
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix
1-indexing Windows

And if you don’t want the 0-indexing for your windows, since 1 is easier to press when switching, add the following as well:

# 1-index Windows
set -g base-index 1

When you are done, be sure

:source-file ~/.tmux.conf
