Name | ### keyReleased()
Examples |
    // Click on the image to give it focus,
    // and then press any key.

    int value = 0;

    void draw() {
      fill(value);
      rect(25, 25, 50, 50);
    }

    void keyReleased() {
      if (value == 0) {
        value = 255;
      } else {
        value = 0;
      }
    }
Description | The keyReleased() function is called once every time a key is released. The key that was released will be stored in the key variable. See key and keyCode for more information. Mouse and keyboard events only work when a program has draw(). Without draw(), the code is only run once and then stops listening for events.
Syntax |
    keyReleased()
    keyReleased(event)
Returns | void
