Seems well worth fixing.

It's easy to get confused because there are both key codes and  
character codes, and the keyCode and charCode functions behave  
differently for different event types.

Two functions to look at to understand the behavior are  
KeyboardEvent::keyCode and KeyboardEvent::charCode.

63232 is the value of NSUpArrowFunctionKey.

It would be good to survey behavior of other browsers, especially  
Internet Explorer, and change our behavior to match more closely.  
Please write a bug report once you have a clear idea what you think  
we should do.
