[Help-smalltalk] Querying smalltalk data using Emacs

[Andrei Stebakov]

In all visual smalltalks you can query any information about the object model.
I wonder if using Emacs alone is enough to learn about classes in GST.
Let's say, how do you jump from a function name to its definition in
Emacs (or do you have to manually find the piece of code)?
What's the workflow of using programming in GST using Emacs?

Thank you,
Andrei
