Using "multiple" option for selectionMode attribute ... is it possible to configure the component for allow ENTER to select/deselect a line? Because when there are many rows to handle, it is better for the user to use only keyboard, not mouse, to this. And also to select a row with ENTER, to move many rows above with DOWN ARROW, and press SPACE to select all the rows between the first mark and this actual row. Is this possible? Or to implement in a next version?
