Affects the operation of the Escape and Enter keys when in editing mode. Normally, Escape while editing an editable cell will abort any changes to that cell and then revert from cell editing to row selection mode. With this flag set, Escape will update the cell and then exit from XTREE. Also, with this flag set, Enter from the last editable cell will exit from XTREE, rather than wrapping back to the first cell.
