Functions

func IsKeysValid

func IsKeysValid(keys []Key) bool

func NewListener

func NewListener(keySettings []Key) func() []bool

func ToVirtualKey

func ToVirtualKey(k Key) uint32

See https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes for reference. Alt, Shift, and Control has 3 codes: overall, left and right. Order of ArrowKeys are different between Ebiten and Windows VK. Order of Page Up/Down are different between Ebiten and Windows VK. KeyNumpadEnter returns VK_RETURN, while main Enter returns the same. KeyReserved0 ~ KeyReserved3 are skipped. Supposed KeyContextMenu stands for Applications key, which is next to Right control Supposed KeyMeta Left and Right stands for Left and Right Windows key. Supposed KeyNumpadEqual returns VK_OEM_PLUS. I guess this is derived from Apple Keyboard.
