I'm certain he means:
Physical key: actual key on keyboard that was pressed (may be
independent of the letter/word/symbol on the key face)
Logical key: this would map to the letter/word/symbol on the key
face, regardless of physical placement on the board

One way to check to see if the enter key has been pressed is to:
[theEvent keyCode] == 0x04C
where 0x04C is the keyCode corresponding to the enter key.
(Is there an Apple defined constant for this key code?)
Another way, found at:
http://developer.apple.com/samplecode/TrackBall/listing9.html
is to do:
NSString *characters = [theEvent characters];
switch ([characters characterAtIndex:0])
{
case NSEnterCharacter:
case NSNewlineCharacter:
case NSCarriageReturnCharacter:
}
My question is which method is the preferred or recommended way to detect
this key in onKeyDown?
Is there a better way?
It really depends on whether you want to detect the physical key or
the logical key.
I am not sure if I understand the difference. Can you expand on this?
