tmux: Create a new window (inside a tmux session).
$ Ctrl-B c
try on your machine
The command "Ctrl-B c" is used in the context of a terminal multiplexer program called "tmux".
In tmux, the "Ctrl-B" combination is the default prefix key that you press before any other command in order to activate the tmux command mode. It's similar to pressing the "Ctrl" key and holding it down while pressing the "B" key.
Once you have pressed "Ctrl-B" to enter command mode, the subsequent "c" press is a command to create a new window. By issuing this command, a new window is created within the current tmux session.
