The SDL virtual key representation.
Defined in SDL_keycode.h
typedef Sint32 SDL_Keycode;
#define SDLK_SCANCODE_MASK (1<<30)
#define SDL_SCANCODE_TO_KEYCODE(X) (X | SDLK_SCANCODE_MASK)
Values of this type are used to represent keyboard keys using the current layout of the keyboard. These values include Unicode values representing the unmodified character that would be generated by pressing the key, or an SDLK_* constant for those keys that do not generate characters.
A special exception is the number keys at the top of the keyboard which map to SDLK_0...SDLK_9 on AZERTY layouts.
