This parameter allows for default key bindings to be cleared before setting custom ones and given the configuration contains all the default bindings, every binding removed from the list will be actually unbinded instead of having to manually do it one by one.
Generated with the following command: 'zellij setup --dump-config'.
According to the documentation, there isn't a configuration file created by default and the procedure requìres you to dump the current configuration (defined in source code) and edit it.
