How activate Load DOM map on Italian keyboard

Hi all,

I’m new entry on this forum and, in general, with the utilization of Katalon Studio.
Currently I don’t understand how activate Load DOM map (I’m using Katalon Shop example)…because on the italian keyboard the combination CTRL+ALT+doesn't capture nothing, while the capture of a single object works in wonderful manner (in my case I have changed the standard combination for this functionality with the combination ALT+a). I tried also to install American language for the keyboard of my WIN 10 laptop, and now I'm able to write the character but the combination CTRL+ALT+` doesn’t work yet.
How can I resolve the problem?

The following is my currently configuration:
O.S.: Win 10 Pro (64 bit version)
Tool: Katalon Studio 7.07 (free version)
Browser: Google Chrome (78 version)

Thanks in advance to all
