I see all these examples in Visual Studio Code where you can pull up a pane with the 10 (or fewer) suggested solutions. But I can't get that in Visual Studio. And I can't find anything about how other than saying Ctrl + Enter should do it.
I've also found on my system that it requires Ctrl+Alt+ instead of just Alt+ in Visual Studio 2022 for the other commands. So maybe something is wrong with my Copilot installation although I didn't do anything other than install it.
