SDL_KeyboardEvent - Keyboard event structure

SDL_KeyboardEvent  is  a  member  of the SDL_Event union and is used when an event of type SDL_KEYDOWN or
       SDL_KEYUP is reported.

       The type and state actually report the same information, they just use  different  values  to  do  it!  A
       keyboard  event  occurs  when  a key is released (type=SDK_KEYUP or state=SDL_RELEASED) and when a key is
       pressed (type=SDL_KEYDOWN or state=SDL_PRESSED). The information on what key was pressed or  released  is
       in the keysym structure.

              Note:

              Repeating SDL_KEYDOWN events will occur if key repeat is enabled (see SDL_EnableKeyRepeat).
