Title: Update selection on quick duplication

When duplicating a rect while in Drawing mode, using mouse + key store (`alt`), selection should be updated:

1. On mouse down on original rect, select the corresponding area.
2. On mouse up, when creating a new area by duplicating, select this new area.
