How to set brightnes for multiple thunderbolt displays at the same time using keys on apple keyboard Is there a way to set the brightness for all displays (thunderbolt displays) connected to a mac using thunderbolt syncroniously.

If I chnage the brightness using F1/F2 on my Mac Wireless Keyboard. Only the Main screen is affected. But I want the displays to stay syncronized.

Any way thought?
This won't let you adjust all of the screens but works for alternates

ctrl-F1 and ctrl-F2 usually change the brightness on the other display (or external display on 10.7).
