Eject Key
"Eject Key to XXX" doesn't work.
The eject key has a delay, so you need to push and hold eject key for a few seconds. Install NoEjectDelay to get rid of a delay.
In addition, the eject key does not support key repeat exceptionally. Unfortunately we cannot add the key repeat feature for the eject key by the limit of the kernel of Mac OS X.
All other keys support key repeat feature. Try "Shift_R to Forward Delete", "F12 to Forward Delete" or others if needed.
Fn Key
"XXX to Fn" doesn't work.
"XXX to Fn" affects the following keys by default.
- Fn+cursor (Home/End/PageUp/PageDown)
- Fn+delete (Forward Delete)
- Fn+return (Enter)
- Fn+jkl... (Keypad)
If you want to use Fn+F1,...,Fn+F12 as Function keys, activate "Fn+Functional Keys to F1..F12".

Note
If you are using F1,F12 as standard function keys, activate "Fn+F1 to Brightness Down" instead.
