Keys are classified in two groups: printable keys, which are keys that have a char representation, such as the 'a' key or the '7' key, and control keys, which are keys that perform an action, such as the arrow keys, the escape key or the backspace key. The space case is a special case, because it is considered both printable and control key.
This class must not be inherited from. Use factory classes and functions to perform custom initialization (see rd::SDLEventFactory).
