tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
  tmux [command]     # Run a command
                     # 'tmux' with no commands will create a new session

    new              # Create a new session
     -s "Session"    # Create named session
     -n "Window"     # Create named Window
     -c "/dir"       # Start in target directory

    attach           # Attach last/available session
     -t "#"          # Attach target session
     -d              # Detach the session from other instances

    ls               # List open sessions
     -a              # List all open sessions

    lsw              # List windows
     -a              # List all windows
     -s              # List all windows in session

    lsp              # List panes
     -a              # List all panes
     -s              # List all panes in session
     -t              # List app panes in target

    kill-window      # Kill current window
     -t "#"          # Kill target window
     -a              # Kill all windows
     -a -t "#"       # Kill all windows but the target

    kill-session     # Kill current session
     -t "#"          # Kill target session
     -a              # Kill all sessions
     -a -t "#"       # Kill all sessions but the target



## Key Bindings

#   The method of controlling an attached tmux session is via key combinations
# called 'Prefix' keys.

------------------------------------------------------------------------------

  (C-b) = Ctrl + b    # 'Prefix' combination required to use keybinds

  (M-1) = Meta + 1 -or- Alt + 1

------------------------------------------------------------------------------

   ?               # List all key bindings.
   :               # Enter the tmux command prompt.
   r               # Force redraw of the attached client.
   c               # Create a new window.

   !               # Break the current pane out of the window.
   %               # Split the current pane into two, left and right.
   "               # Split the current pane into two, top and bottom.

   n               # Change to the next window.
   p               # Change to the previous window.
   {               # Swap the current pane with the previous pane.
   }               # Swap the current pane with the next pane.

   s               # Select a new session for the attached client interactively.
   w               # Choose the current window interactively.
   0 to 9          # Select windows 0 to 9.

   d               # Detach the current client.
   D               # Choose a client to detach.

   &               # Kill the current window.
   x               # Kill the current pane.

   Up, Down        # Change to the pane above, below, left, or right.
   Left, Right

   M-1 to M-5      # Arrange panes:
                   #    1) even-horizontal
                   #    2) even-vertical
                   #    3) main-horizontal
                   #    4) main-vertical
                   #    5) tiled.

   C-Up, C-Down    # Resize the current pane in steps of one cell.
   C-Left, C-Right

   M-Up, M-Down    # Resize the current pane in steps of five cells.
   M-Left, M-Right



### Configuring ~/.tmux.conf

  tmux.conf can be used to set options automatically on start up, much
like how .vimrc or init.el are used.

# Example tmux.conf
# 2014.9


### Keybinds
###########################################################################

# Unbind C-b as the default prefix
unbind-key C-befix C-a

# Return to previous window when prefix is pressed twice
bind-key C-a last-window
bind-key ` last-window

# Allow swapping C-a and ` using F11/F12
bind-key F11 set-option -g prefix C-a
bind-key F12 set-option -g prefix `

# Activate inner-most session (when nesting tmux)
# to send commands
bind-key a send-prefix

# Index Start
set -g base-index 1

# Window Cycle/Swap
bind e previous-window
bind f next-window
bind E swap-window -t -1
bind F swap-window -t +1

# easy-to-remember split pane commands
bind | split-window -h
bind - split-window -v
unbind '"'
unbind %

# moving between panes with vim movement keys
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R
