Use KEY_RESERVED for them and in your driver, special case it to not output EV_KEY events for KEY_RESERVED, but still output the EV_MSC/MSC_SCAN. This allows userspace to reprogram them to normal keys (or even to KEY_UNKNOWN) if it wants. > Perhaps the BTN_MISC codes are better suited for these keys?
