Xcode intellisense meaning of letters in colored boxes like f,T,C,M,P,C,K,# etc

[hiprakhar]

Recently, I have started using Xcode 4 for developing iOS apps.

In Xcode intellisense's autocomplete box, there are some letters in colored boxes before every suggestion. I know that they represent the property of the word we are typing like f,T,C,M,P,C,K,# etc. enter image description here

Is there some kind of glossary available to find their quick meanings?

Meanings of f,C,T,# are understandable (function, class etc) but there are many others which are not very intuitive.

Please suggest. I would be grateful for all your answers.

Dont we have any reference page by apple for explaining intellisense's letters? Thats really strange...

IntelliSense is Microsoft's implementation of code completion, I'm not sure if there's a specific name for it in Xcode.

There's a huge guide on Xcode in the docs that probably covers those icons: Loading…

They are pretty self explanatory, E is for enum, T is a typedef, f a C function, # define, C a class and so on. But there's loads of them in the data modeler, call stack and Debug navigator and so on.

EDIT: I think the code completion popup has a quick help button (far right next to each item), try clicking or mouse over it and see the description/help, the type corresponding to the icon might be there.
