In the Image a good example is the InitAbilityActor info function call or the Binds declaration. For the info you'll see "InOwnerActor: this", so the "InOwnerActor" label placed there is what I'm asking about. I was watching an Unreal Engine tutorial and saw the author casually doing this, and I didn't know that it existed. I'm including a screenshot of what I mean. As you can see, it's not a tooltip or intellisense related (I don't think). Is it a Visual Studio feature (I have VS2019), a new option in the language, or some VS add-on that lets you do that? I do like that feature in Python, so if it's possible in C , that would be great.

The screenshot is most likely showing the inlay hints feature of the Resharper C addin.

I am not aware of any other readily available addin or built-in option that allows this for C . Note that Visual Studio supports it out-of-the-box for C# and Visual Basic since VS 2019 v16.8, but not for C .
