+#### `stream-quality`
+
+Switch stream quality. This is just a basic re-assignment of `ytdl-format` mpv property from predefined options (configurable with `stream_quality_options`) and video reload, there is no fetching of available formats going on.
+
 #### `open-file`
 
 Open file menu. Browsing starts in current file directory, or user directory when file not available.
