Prevent Exiting Fullscreen Mode in Chrome During Online Exams

[adidasreveal]

Hello,

To conduct a certification exam, I need to launch Chrome in fullscreen mode without displaying the address bar or browser controls, in order to prevent candidates from searching for answers online. I already know how to enable fullscreen mode.

However, pressing keys such as Esc, F11, or F12 allows users to exit fullscreen mode or open developer tools. I would therefore like to disable these keys during the exam session.

Does anyone know if this can be achieved using JavaScript?

Best regards,
