If it is desireable to unfold some contiguous range of cells rather than the whole ray and the user notes the cell at which unfolding should end and then clicks the cell where the unfolding should start, the whole ray will initially be modified, but if the user subsequently clicks on the noted final cell the unfolding will be only within the range defined by the first and second cells clicked as long as the two cells clicked are in the same column.
Folding operations on a ray from the clicked cell to the end are accomplished with the "- Fold Ray >" and "+ Fold Ray >" options.
