    B5.2.5.3 Multimedia keyboards with extra hot buttons conform to the defined scan codes or HID usages

    Microsoft has defined extended scan codes for PS/2-compatible multimedia keyboards, and the USB HID Device Working Group has defined the consumer controls page. Hardware vendors should conform to these defined values and use their default functionality in order to ensure a good user experience following an upgrade or if the user doesn’t install any supplemental software. Additional software/drivers can be written to provide software remapping functionality.

    Keyboard manufacturers must use consumer control or vendor-specific, top-level collections for HID hot buttons. For PS/2, vendors must use only the Extended Scancode set for hot buttons and must provide a filter driver or use a Keyboard DLL hook to perform hot-button remapping.
