tmux
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.

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

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