Hi to all, and please help me 
Peculiar problem stroke me yesterday:
On my late 2009 Mac Mini running Mavericks, I have external long keyboard (flat type) and it somehow lost two keys:
"O" and "right command-key" as in nothing happens when pressed.
When I pulled on screen keyboard, there are two other keys highlighted as orange, I wonder if theres an analogy for my missing keys?
Ive already looked under universal access, and there shouldn't be any key-shortcuts assinged for those keys particular.
please see attached screenshot and thanks in advance.
