I just began using my new Mac and Magic Mouse but I can't seem to copy and paste while trying to add more stars to the game I'm studying on.

game.js
var game;
var player;
var platforms;
var badges;
var stars;
var poisons;
var cursors;
var jumpButton;
var scoreText;
var livesText;
var finalMessage;
var won = false;
var gameOver = false;
var currentScore = 0;
var lives = 3;
var winningScore = 100;

function createStars() {
    stars = game.add.physicsGroup();

    starCreate(425, 100, 'star');
    starCreate(315, 100, 'star');
    starCreate(175, 200, 'star');

}

function createPoisons() {
    poisons = game.add.physicsGroup();

    poisonCreate(675, 275, 'poison');
    poisonCreate(450, 375, 'poison');
    poisonCreate(375, 475, 'poison');

}


function createPlatforms() {
    platforms = game.add.physicsGroup();

    platforms.create(300, 150, 'platform');
    platforms.create(400, 250, 'platform');
    platforms.create(100, 250, 'platform');
    platforms.create(500, 350, 'platform');
    platforms.create(400, 450, 'platform');
    platforms.create(300, 550, 'platform');

    platforms.setAll('body.immovable', true);
}

function starCreate(left, top, starImage) {
    var star = stars.create(left, top, starImage);
    star.animations.add('spin');
    star.animations.play('spin', 8, true);
}

function poisonCreate(left, top, poisonImage) {
    var poison = poisons.create(left, top, poisonImage);
    poison.animations.add('bubble');
    poison.animations.play('bubble', 8, true);
}

function starCollect(player, star) {
    star.kill();
    currentScore = currentScore + 20;
    if (currentScore === winningScore) {
        won = true;
    }
}

function poisonCollect(player, poison) {
    poison.kill();
    lives = lives + 1;
    if (lives === 0) {
        player.kill();
        gameOver = true;
    }
}

window.onload = function () {
