I didn't know where else to post this, I'm new to this site. But to sum up my issue, I spilled alcohol on macbook keyboard, so I bought and just received a wireless keyboard which I paired with my computer, but the shortcuts at the top of my keyboard aren't doing what they should be doing. I went into system preferences and was able to change it so I can change the brightness, but from F7 to F12, where you are suppose to be able to change the song, play/pause, mute and turn the volume up and down, it does other things. I've tried adding an application to my keyboard shortcuts, added iTunes and then wrote "Volume Up" and set it to F12, and "Volume Down" and set it to F11, but it didn't work. Is there certain words I have to put for it to work? Thanks.
