Mac OS X 10.0: Using the Keyboard Control Panel in Classic

A Classic application must be in the foreground for Classic-defined function keys to take effect.
Symptom

The function keys do not behave as defined in the Classic Keyboard control panel.


Solution

Function key actions defined in the Mac OS 9.x Keyboard control panel only work when the selected and running (or "foreground") application is a Classic application.

Mac OS 9.x keyboard definitions do not have precedence when a native Mac OS X (Carbon or Cocoa) application is in the foreground.
