works as the Ctrl key, and the Ctrl
key works as the Fn key.

selected, you need to press the Fn
key to return the computer from sleep
mode to normal operation.
If you select "Enabled," you can press
the Fn key to keep it in a pressed
condition, then press the desired

pressed the Fn key twice, the state
is locked until you press the Fn key
again.
