Hi all,

I have a table in the main window and want to show different information
when a row is selected. I have implemented setAction so it works when a user
selects one row by clicking in it, but I have no idea how to update the info
when the user selects the previous/next row by pressing up/down arrow.

I have read all the apple document about keyboard handling but I cannot do
my application works. I have tried many things but nothing worked.

Thanks in advance,
Tackel.
