The mode, by default, creates a new pane and buffer "*erlang*" when I hit C-C C-K to compile an erlang file. (as seen in the attached screen shot)
What is the easiest way to switch between these two panes?
I do not think "C-x b" is applicable in this case…

I don't understand why authors said that Code Listing 9.1 from "Programming in Scala" use closure. In chapter 9, they show how to refactor code into more less duplicated form, from this original code:
