You can print the voice commands to a .pdf file named "Voice commands.php", saved in the folder "Documents \ PP Play ByVoice 2", pressing the related button at the bottom of the Test window. Once created the file you can show it pressing the "Show .pdf" button.

NOTE: if you change a voice command, before to print the new list you must apply to confirm the change. Or to close and reopen the window.

This feature is only available on Windows 10 or lather.
