A Boolean value indicating whether Full Keyboard Access is enabled in the Keyboard preference pane.
- macOS 10.6+
The value of this property is
YES if Full Keyboard Access is enabled or
NO if it’s not. You might use this value to implement your own key loop or to implement in-control tabbing behavior similar to
NSTable. Because of the nature of the preference storage, you won’t be notified of changes to this property if you attempt to observe it through key-value observing; however, accessing this property is fairly inexpensive, so you can access it directly rather than caching it.
