@Lyosha @james Tried to find explanation around and that is not much of help. I feel exactly like I felt when I have run Lisp machine emulator - like monkey sitting in front of space shuttle control panel, randomly pressing keys and mouse and nothing happens!
But, i managed to type in scratch buffer and loaded configuration file that I can edit, but that's about it. I am lost.
At least standard EMACS is frendly enough that I could browse dirs, open files, edit them and save them.
