Keyboard shortcut for 'down' in recent files popup?

Hi,

I have Control-N bound to "down", but when I hit Command-E to get the "Recent Files" popup, I have to use arrows to move up or down. Other popups, like Command-N to navigate to class, work as I'd like: I can use Control-N/P to move up and down.  Is there a way to get Control-N to move down in the Recent Files popup list?

I've probably asked this before... I feel I'm always forgetting these things as I switch from Xcode to IDEA.
