Disable row selection using up/down keyboard buttons

Dear all,

is there a way to disable the possibility to change the row in a table using up/down keyboard buttons? In our case every time the user’s selection changes we have, among others, to reevaluate which buttons should be enabled and which should not. So when the user goes up or down the rows using keys this would be done for every row change, if I am not mistaken (using ValueChangeListener). So I would like to restrict value changes to clicks (only using a ClickListener).

Thanks in advance
