tmux

tmux is a software application that can be used to multiplex several virtual consoles, allowing a user to access multiple separate terminal sessions inside a single terminal window or remote terminal session.

configure tmux

Edit ~/.tmux.conf

unbind C-b
  set -g prefix C-a
  bind C-a send-prefix

Those changes will make tmux the same shortcut as screen, his older brother.

Shortcut press ctrl+a and:

c create window
w list windows
n next window
