My F14 and F15 keys don work as triggers under Tiger or Leopard, why?
A. As of 10.4.11 (Tiger) and 10.5.5 (Leopard) Apple has changed how these keys work. Newer keyboards that have dedicated brightness keys with the graphic above the Fkeys the F14 and F15 will just work. If you have an older keyboard you can now go into the Keyboard & Mouse System Preference and under the Keyboard Shortcuts tab you will find a new item named “Display” where you can reassign the default F14 and F15 to something else, like adding Control to each of them so the raw F14 and F15 can be used by QuicKeys.
