Type Win32Key
type Win32Key struct {
VirtualKey uint16
ScanCode uint16
Unicode uint16
ControlState uint16
Repeat uint16
}Win32Key is the Windows console INPUT_RECORD data of a key event: the virtual-key and scan codes, the UTF-16 code unit, the control-key state and the repeat count. It is set only on Windows, and a terminal forwards it only when the program enabled win32-input-mode (CSI ? 9001 h). Other platforms leave it zero.
