Set up tmux panes in Cloud Shell
You are going to configure three Cloud Shell panes so that you can issue commands in one pane and watch the effects on the two clusters in the other panes.

Split the session screen with the tmux utility built-into Cloud Shell by typing <Ctrl>+b, then %. You should see 2 panes in the Cloud Shell.

Any time you interact with tmux, you'll start with the <Ctrl>+b combination, which signals a command to tmux.

Switch to the left-hand pane by typing:
