# set_synchronize_panes

> Change tmux state; no client-supplied executable input. Turn synchronize-panes on or off for a window. Input typed into one of its panes then reaches the synchronized input cohort: every pane whose effective synchronize-panes setting is on. A pane without a setting of its own follows the window; one with its own setting stays included or excluded either way.

Server behavior and tool contracts may change. Tool availability depends on the server configuration.
