What does the Preview command do? The keyboard shortcut for it is Ctrl+Alt+/. When I was customizing a toolbar I noticed the command (just called Preview) in the Edit commands. I cannot find anything describing it or even anything else mentioning it. I added it to a toolbar. In a C# file when I click the icon I get a message saying no smart edits found but I cannot find C# code from which I get anything other than no smart edits found.
I am using VS 2022. At the time I posted I was using 17.0 I think but a few minutes ago it was updated to Version 17.1.0.
The following shows the Add Command window and the specified Preview command.
The following shows the results (saying no smart edits found) in an edit window of when I click the Preview icon I added to a toolbar.

Hi, which version of Visual Studio are you using? Could you share us any screenshots about your issue?

I believe it's the IntelliCode suggestions feature.
It might be an IntelliCode thing. If it is then that page you provided sure does not mention the command or anything about previewing. I updated my question because I discovered the command is enabled in a C# file but I cannot find C# code from which I get anything other than no smart edits found.
It's not a feature I have any particular interest in (I was surprised it'd been done when I read about it), I try never to repeat myself writing code, so I can't say I've ever noticed it show up for things I've done.
Now I've said that, it'll probably happen :)
... and blow me, here it is occurring with my trying to minimize someone's duplicated code:
typical!
I cannot find C# code from which I get anything other than no smart edits found.
For example, the code is 'int x; int y;'. Then the first int is changed to float, and the caret is moved to the second int. The <Ctrl+Alt+/> displays a suggestion: "→float". The <Tab> can be used to accept it. The <Ctrl+Alt+.> instead of <Ctrl+Alt+/> applies the suggestion without previewing.
Hello,
I agree with DavidLowndes-6766.
Based on my testing, I suppose the preview will track your local edits and review the multiple locations where you might need the same change.
If it shows “no smart edits found”, it may not find the place that needs to be changed.
You can try to disable the feature by Tools > Options > IntelliCode > General > Suggestions > C#: Disabled.
If you need more content information about the feature, you can submit feedback in the intellicode page.
Thanks for your understanding!
Sincerely,
Anna
