If the Auto wrap action has been activated, then, when the selection indicator reaches the end of a row, it will automatically jump to the first cell of that row. At the end of a column, the selection indicator will jump to the first cell of that column. Conversely, the selection indicator will jump to the last cell of a row or column as soon as the beginning of the row or column has been reached. If this action is not activated, then the selection indicator will remain on the first or last cell of a row or column.
