Switch between text inputs on dashboard

Hi! I am creating a Dashboard and I would like the user to interact using only a bar code scanner.

The problem is, when I deploy the flow, is it possible to place the "text cursor" in an specific text input widget without using the mouse to click, so that the first scan with the bar code scanner is writen there directly?

Once it is writen, is it possible to jump to the next one without using the computer keyboard (tab) or the mouse?

Thanks for the help!
