coverity message: sign_extension: Suspicious implicit sign extension: "keydata.Key.ScanCode" with type "UINT16" (16 bits, unsigned) is promoted in "keydata.Key.ScanCode << 16" to type "int" (32 bits, signed), then sign-extended to type "unsigned long" (64 bits, unsigned). If "keydata.Key.ScanCode << 16" is greater than 0x7FFFFFFF, the upper bits of the result will all be 1.
