SDL_KeyboardEvent - Keyboard event structure
type SDL_KEYDOWN or SDL_KEYUP
state SDL_PRESSED or SDL_RELEASED
keysym Contains key press information
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.
Repeating SDL_KEYDOWN events will occur if key repeat is enabled
