Playhead
The playhead is a vertical line that moves during playback, showing the current rhythmic position. It is also known as a playback line.
The playhead is shown at all times in Play mode, but you can also see it in other modes during playback. You can also choose to show the playhead when playback is stopped in other modes in the Play section of the General page in Preferences.

Dorico automatically keeps the playhead in view during playback by moving it along with the music, but you can also move the playhead manually. Dorico tries to keep systems in the same place on the screen when it scrolls along with the playhead for consistency as you follow your music.
