Individual periods can be moved using drag&drop in the same way as in the timetable modus.
Empty green fields mean that a move to this position is possible without creating a clash.
If you shift a period using drag&drop, the move will be displayed in the substitutions window. In the example, the physics period for 3b was moved from Mo-1 to Mo-6.
Moving part of a coupling
If a teacher from a coupled lesson with 2 or more teachers is to be moved, you can perform this in the teacher's timetable. The example shows how on teacher Gauss' lesson was moved from a coupling between Gauss and Curie from We-5 to We-6.
