shift/move playhead according to the timeline by pressing key commands in Write mode when playback is stopped

Dear advanced users and developers,

Is there a way to move (shift) the playhead according to the timeline in Write mode by pressing key commands when playback is stopped?
The orchestral piece which I am currently working with is a bit complicated and I would like to see vertical pitches in each semiquaver.
It would be greatly appreciated if someone gives me a tip!

You can move the playhead to the start of the selection with Alt+P, and you can move the playhead forward and backward by frames (see Play > Next Frame/Previous Frame in the Key Commands editor). I believe you can also use the fast-forward and rewind commands when playback is stopped, which I think moves the playhead by an interval of 1 second in either direction.

Thanks! It is great!
