Part Markers are easy.

Those Blue or Green (and there are other colors for Multi-Styles) blocks on the bar numbers in the chord grid.

Well, the blue ones are A variation of the style and the green ones are B variation.

If you leftclick one time on a bar number, it will turn blue and become A substyle. It will also instantly create one of those new lines on the chord grid.

If you are in a green area, just click it again to turn it green.

Or click it one more time to turn it off.

A part marker that is the same color will only force a drum fill before that area.
