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

: # 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
[ # Enter Copy Mode to copy text or view history.
