Tmux

Tmux is a windowing manager that allows a user to utilize space. Its predecessor is screen. An major advantage is its use of sessions, which leverages nohup -- a utility that keeps tmux running in even if the user has exited.

Shortcuts

The default prefix is [ctrl] then b which move tmux into a context.

Action	Shortcut
Split horizontally	[prefix] then "
Split vertically	[prefix] then %
Move between windows	[prefix] then [arrow]
Scroll model	[prefix] then [
Rename session	[prefix] then $
Detach session	[prefix] then d
