This is a command developed especially for the commercial software uGin'irov. When you use this command, you can enter Auto Mode from the menu. It is similar in concept to the uskip to next choicev option, but it displays characters much more slowly (with a delay defined by automode_time). So it is almost like a mode in which the computer reads the text to you.

You can effectively adjust sound playback volume from the menus while Auto Mode is still progressing (MP3(BGM) voice(DWAVE 0) SE(DWAVE 1`) are all still active, and adjustable).

There are future plans to add further functionality to this command, and to make things more rigorously conformant to predefined syntaxes.
