# Tmux - synchronize the input of all panes within a window So, you've got a tmux window with 10 panes, and you want to clear the panes, switch to a different directory, stop multiple process, and so on. There is a simple way to do it: `Prefix` + `:set synchronize-panes on` *Just in case: the default `prefix` is `CTRL` + `b`.* The input of all panes within a window will be synchronized until you turn it off again: `Prefix` + `:set synchronize-panes off` ### Create keybinding If you need this function often, you could create a simple keybind for it. For examples, if you want to add it to `Prefix` + `e`, add this to your config file: `bind e set-window-option synchronize-panes` Load this config with `Prefix` + `:source-file ~/.tmux.conf` (or wherever your config file is located) and you can turn pane synchronization on and off with `Prefix` + `e`. ---
