How to Trigger Keyboard shortcut (ctrl+alt+R) using javascript?

Question

I am trying to create a webpage that should be able to record the screen automatically. I am using "Screencastify" chrome extension to record the screen. Here we need to use Ctrl + Alt + R to start/stop recording. Is there any way to start/stop recording from a page's javascript? Please let me know your thoughts on this.

Answer 1

I'm afraid not.

Even if Screencastify has some API exposed (eg a custom event you could raise), it would probably run into problems that recording screen requires an explicit invocation of the extension by the user.

That said, a quick glance shows that there is no such API exposed.
