keypressed ( expression )
return boolean_expression or integer_expression
The KeyPressed function returns a true or false value if a key is currently pressed, or returns the number of keys that are currently being pressed. Unlike the key function that clears the keyboard buffer, the KeyPressed function does not. This allows for the creation of much more responsive games and other uses of the keyboard.
See the key function for a list of common key codes or see here for a complete list codes.
