The command "Ctrl-B w" is used in the context of a window manager called tmux.

Tmux is a terminal multiplexer, which means it allows multiple virtual terminals within a single window. Each terminal runs independently and can be split into panes or organized into windows.

"Ctrl-B" is the default prefix key in tmux, which means you need to press it before issuing any other command.

In this case, "Ctrl-B w" is used to list and manage the windows within a tmux session. When you press "Ctrl-B" followed by "w", tmux will display a list of all the windows currently open in the session. You can navigate through the list using the arrow keys and press Enter to switch to a different window.

This command is useful when you have multiple windows open in tmux and want to quickly switch between them without having to close or resize existing panes.
