I know that on the new macs (i.e. quicksilver) this is a media eject key that works quite nicely. I was wondering if it would be somehow possible to implement this feature on my iBook. I realized that this feature is similar to the sound and brightness controls that replace some of my iBook's function keys. These keys are not changeable in the keyboard panel, so i was thinking that if i replaced my keyboard preferences file with one from a quicksilver, it view one of my iBooks function keys as an eject media key. Think this is possible or is this a hardware dependant feature?
