Visual Studio C++ intellisense Function Info - How to interpret the various delimiters, types, and acronyms

Question

I am experienced with classic C, C++, but I am now learning how to use the various "newer" resources in the C++ Standard Library.

In Visual Studio, when I start typing a function name, I get a "quick info" definition, with several fields. Usually the function name is preceded by a long list of libraries, parent classes, template typename(s), etc.

How do I interpret these various fields?

Using the std::tuple get<>() function, here is a typical example for VS intellisense popups (with cursor positions shown in red .)

I understand that intellisense is first highlighting the template typename, then highlighting the function argument(s).

But how do I make sense of the other fields, preceding the function-name?

For example: constexpr std::tuple_element_t<_ldx, std::pair<_Ty1, _Ty2>> & get<_Idx,_Ty1,_Ty2>(...)

Answer 1

What is preceding function name is it's return type, which in this case is pretty long template with it's arguments.
