What does IntelliJ Idea or Android Studio offer on Alt-Enter?

Question

In the documentation, I found that by Alt-Enter Android Studio offers the following options:

But there is another group of proposals that are neither one nor the other. For example, when I write an assignment to an as yet undefined variable.

What kind of animals, where to read about them, and whether they can customize?

I would say that this is just the Intention Action and judging by the color of the Quickfix suggested light bulb
jetbrains.com/help/idea/2016.3/disabling-intention-actions.html And I can not find this action in the list in the settings.
I never thought about it, but I think that the fastest and most correct way out would be to ask the creators of IDEA.
There are great people working there - they will be happy to help.
But if you start the inspection with your hands, there will not be a word in the list of problems found about this variable, but it will be about less significant problems, such as unused fields and unnecessary imports.

The support responded that it was after all Intention Actions, but hard-coded, so they cannot be seen in the settings and cannot be turned off.

It's Intention Action since Alt + Enter is a shortcut for Show Intention Actions. Some of them are hardcoded and cannot be disabled.
