-   * A String system variable that contains the value of the last mouse button
-   * pressed.
+   * An object that tracks the current state of mouse buttons, showing which
+   * buttons are pressed at any given moment.
    *
-   * The `mouseButton` variable is either `LEFT`, `RIGHT`, or `CENTER`,
-   * depending on which button was pressed last.
+   * The `mouseButton` object has three properties:
+   * - `left`: A boolean indicating whether the left mouse button is pressed.
+   * - `right`: A boolean indicating whether the right mouse button is pressed.
+   * - `center`: A boolean indicating whether the middle mouse button (scroll wheel button) is pressed.
    *
    * Note: Different browsers may track `mouseButton` differently. See
    * <a href="https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/buttons" target="_blank">MDN</a>
    * for more information.
