It is easy as pie ;) Go to Actions menu, in filter type "Go to marker" and you'll have a set of 10 markers, to which you can map a pc or midi keyboard commands. Simply click "add" at the bottom left of the selected action and move/press the controller/note/footswitch u want to control that action with. Or if you simply want to go to "next marker", use that function instead with the footswitch. Also under Options menu choose "Smooth seeking (seeks at end of measure)" to remain in time sync when switching the position.
