 ## Saving filters in gam.cfg
-If you define a value for `csv_output_header_filter`, `csv_output_header_drop_filter`, `csv_output_row_filter`, `csv_output_row_drop_filter` or `csv_output_row_limit` in the `[DEFAULT]` section of `gam.cfg`,
+If you define a value for `csv_output_header_filter`, `csv_output_header_drop_filter`, `csv_output_header_force`, `csv_output_header_order`, `csv_output_row_filter`, `csv_output_row_drop_filter` or `csv_output_row_limit` in the `[DEFAULT]` section of `gam.cfg`,
 it will apply to every `gam print` command which is probably not desirable. You can store them in `gam.cfg` in named sections.
