I found that the keyDown: + interpretKeyEvents method wouldn't work 
with the NSTextFieldCell so I ended up overriding endEditing: (tv is 
an outlet to the parent tableView of the cell):

- (void)endEditing:(NSText *)textObj {

    int editedRow = [tv editedRow];
    int editedColumn = [tv editedColumn];
    int numberOfRows = [tv numberOfRows];

    editedRow ++;
    editedRow = (editedRow == numberOfRows ? 0 : editedRow); // 
Selects the first row when the las one is reached.

    [super endEditing:textObj];

    // Select the row (needed to avoid an exception to be raised).
    [tv selectRow:editedRow byExtendingSelection:NO];

    [tv editColumn:editedColumn
         row:editedRow
    withEvent:nil
       select:YES];
}

It works, but is it the best way? It looks more like a workaround than 
like the regular way of customizing "the tab-loop behavior"... And 
what if I want to take different actions according to the key that 
ended the editing?
