Is here some similar page which gives such kind of information / organized in different way? Or is this the only source?

Each class list all its methods.

What does mean $ is it global variable? I thought it is array, but now I see they use it in different way.

This:

results = inputbox prompts, values, $exStrings.GetString("Cost Estimate")

What is inputbox, does not look like method of global scope

$ is global variables, yes. Avoid them.

inputbox is an alias for UI.inputbox defined in sketchup.rb which comes with SketchUp. (I use UI.inputbox simply because of potential problems of relying on the methods in the global namespace.)

Hm. I see. Sketchup.rb is short, so it will not be problem to remember it. And where is definited UI?

That's from the API - defined in C++.
Look to the documentation: https://developers.google.com/sketchup/docs/ourdoc/ui
