I'm having trouble with my Apple bluetooth keyboard for several days after upgrading my system to Lion. In a weird way, neither right shift+; nor right shift+' is working. I have no trouble with the left shift key, or the right shift key with any other keys. Can anybody give me some suggestion to solve this?
The most common cause of one key not functioning is that it has been somehow set as the trigger for Text to Speech or Speech Recognition in system preferences/speech.
