Thanks for your reply, Daniel. I've learned something, but didn't get me all the way. I can put a handler on the containing div of the table and I get mouse click event that way, but the keydowns don't turn up. Like the table's scrollbar is consuming it...
If I put the handler on the whole document, I get the keydown events - always. But when I try use document.activeElement to find the one with the focus it returns rational result for all other elements on my page - other than the goggle table. If my table has the focus, activeElement just returns the body element like if nothing had the focus :-\ So I guess I have use some other approach for this.
