I read it - thanks.

The Green and Blue part markers are used ot change the substyles. Usually 4.
Additionally:
Each style has at least an A and B substyle.
Substyle A is usually initiated by a blue marker and substyle B is indicated by a blue marker.

But by default "The substyle will change automatically on second choruses when the "Vary Style in Middle Choruses" song setting is selected.

In these cases the substyle changes without any indication on the Chord Sheet, or instruction from a user.
