Fix incorrect handling of extended scan codes on Windows #343

Closed drmfinlay closed 3 years ago

drmfinlay commented 3 years ago

This changes the KeyboardInput struct in sendinput.py to use the MAPVK_VK_TO_VSC_EX map type when translating virtual key codes on modern versions of Windows. The KEYEVENTF_EXTENDEDKEY flag is added only if the scan code has a high byte of 0xe0 or 0xe1, as per the documentation for MapVirtualKeyExW() (available here).

This removes the hardcoded list of extended keys.

This fixes (again) issue #287.
