has never worked and no one has complained. It is still possible to set a default tabs (v. spaces) indent 'manually' via config-main.def (or to turn on tabs for the current EditorWindow via the Format menu) but IDLE will encourage indentation via spaces. Enable setting the indentation width using the Options dialog. Bug # 783877 Remove some commented out old code from configDialog.py (related to old methods for invoking the HelpBrowser).
