On my dev Opera (84.0.4295.0), Ctrl+Shift+C is assigned to Inspect element, which opens Dev tools also. I have not reassigned any keys here.
This means that generally keys are not changed; of course some earlier versions could have different assignments. Few versions ago Ctrl+Shift+I was for Inspect element; why they changed shortcuts, I have no idea.
At my work I have set F12 for dev tools - more compatible with other browsers.
