Common Sense

Tmux is an open-source terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window. It is useful for running more than one command-line program at the same time.

Terms:

• Session: A session can have multiple windows.
• Window: A window can have multiple panes. The is mismatch between current understanding of a "window" and the term "window" in tmux, which is more like "tab". A session is more like a window that have multiple tabs.
• Pane: You can split a window into multiple panes.

Master key: Ctrl+B. Inside a tmux session, to navigate around, you will need to press Ctrl+B first before hitting any actual command keys.
