Ungroup Cells/Group Normally
ungroups the selected sequence of cells.

Details Details

Ungroup Cells/Group Normally is only available when manual grouping (Cell ► Grouping ► Manual Grouping) is selected.
When there are subgroups within the selection, they are left as is.
If the selection is a range of cells at the bottom of a group but not the whole group, Ungroup Cells removes those cells from the group, but does not destroy the whole group.
