iTunes 11.0.5 function keys not working (f7,f8,f9)

It has to do with when you are using Google Chrome, something about Google Play Music takes control of the keys. See this link to fix the problem.

And thank you Apple Support (specifically Sem) for helping me figure that out!

Does iTunes jump to the next song if you tap the left or right arrow keys?

Try double checking or changing the fucntion keys, use this as a guide -> Mac OS X: How to change the behavior of function keys

1. Choose System Preferences from the Apple menu.
2. From the View menu choose Keyboard (or Keyboard & Mouse in Mac OS X v10.5.8 and earlier).
3. Click Keyboard, if necessary.
4. Enable "Use all F1, F2, etc. keys as standard function keys."

More info about iTunes keyboard shortcuts here -> iTunes 11 for Mac: Keyboard shortcuts

If you haven't made changes in System Preferences > Keyboard, then check iTunes' Help > Keyboard Shortcuts to see methods to do what you used to do with the function keys.

If you haven't made changes in System Preferences > Keyboard, I don't know why they stopped working, but the Help offers reasonable workarounds / substitutions.

My problem was that a Chrome extension had hijacked the controls. You can turn them off and free iTunes: https://major.io/2014/07/30/playpause-button-stopped-working-in-os-x-mavericks/

I did everything that was suggested, and I don't have chrome on my mac. f7 to f9 still are not working... 😟

nvm, I just restarted my computer and then it works ;p

Great that works for me. Thanks a lot

Thanks, this has been driving me mad. Chrome had hijacked my F Keys too.
