keyevent

In my GWT program I have a table that has a selected row. I'd like to move the row selection with the up- and down-keys on the keyboard. So I have to catch the key events somehow.

The GWT docs handle key events in input fields only. But I don't have an input field!

Is this possible at all? Maybe it is a DOM/Javascript restriction that GWT cannot work around...
