<p>The 'Fork' operation (found in the 'Flow control' category) splits up the input line by line and runs all subsequent operations on each line separately. Each output is then displayed on a separate line. These delimiters can be changed, so if your inputs are separated by commas, you can change the split delimiter to a comma instead.</p>

<p>The 'Magic' operation uses a number of methods to detect encoded data and the operations which can be used to make sense of it. A technical description of these methods can be found <a href="https://github.com/gchq/CyberChef/wiki/Automatic-detection-of-encoded-data-using-CyberChef-Magic">here</a>.</p>
