HTML

<!doctype html>
<html lang="en">
<head>
    <style>
        h1 {
            color: green;
        }
 
        body {
            background-color: lightgreen;
            text-align: center;
        }
 
        div {
            padding: 20px;
        }
 
        p {
            font-size: 25px;
        }
 
        button {
            background-color: #4CAF50;
            /* Green */
            border: none;
            color: white;
            padding: 15px 32px;
            text-align: center;
            text-decoration: none;
            display: inline-block;
            font-size: 16px;
        }
    </style>
 
    <script src=
"https://code.jquery.com/jquery-3.5.0.js">
    </script>
</head>
 
<body>
    <h1>GeeksForGeeks</h1>
 
    <p>
        Click here to check whether
        Meta key was pressed of not.
    </p>
 
    <button value="Test" name="Test" id="check">
        click Here!!
    </button>
 
    <h1 style="color:black;" id="display">
          ****
    </h1>
 
    <script>
        $("#check").click(function (event) {
            $("#display").text(event.metaKey);
        });
    </script>
</body>
</html>

Output:

Before clicking the button – There is only one button named ‘click me please!’.
After clicking the button: After clicking the button if you see true then it indicates that you did press a meta key but in case, you can notice that your output is false it indicates that you didn’t press any meta key.
