<P> While it is most common for the Fn key processing to happen directly in the keyboard micro-controller , offering no knowledge to the main computer of whether the Fn key was pressed , some manufacturers , like Lenovo , perform this mapping in BIOS running on the main CPU , allowing remapping the Fn key by modifying the BIOS interrupt handler ; and Apple , in which the Fn key is mappable and serves other uses too , as triggering the Dictation function by pressing the Fn key twice . </P>
