I use Easy Access to hold down one key while I press another. On the PowerBook G3 Series I have turned on Sticky Keys in Easy Access and am trying to get it to hold down the function (fn) key. It does not seem to be holding that particular key.

Easy Access does not currently recognize the fn key as a valid modifier key. Apple is aware of this limitation.

Note: the fn key on a PowerBook G3 keyboard should not be confused with function keys F1 through F15. These keys are appropriately not modifiers.
