Too many monitors...

[Killerbob]

I am hooking up an Apple Thunderbolt Display AND an Apple Displayport Display to my MacBook Pro (including USB from the ACD). I also have the external Apple keyboard connected. The MBP screen is main, the ATD is 2nd, and the ACD is 3rd.

When I press F1/F2, that controls brightness on the on the ATD, and CTRL-F1/F2 the brightness on the MBP. What is the keycombo for the ACD

You may be better off asking in the Mac pro sub forum where multi monitor madness exists far more than here.

I have a link here in my old bookmarks that may be useful for volume:

Have you tried option f1/f2
