Hi Naveen,
I tried this procedure and I get the Vim editor GUI.But there is something wrong.....in Vim if we push 'y' then it will print 'z' and vice versa.
the 'ports/run/noux_vim.run' script configures the 'terminal' to use the German keyboard layout. You may prefer to remove the corresponding argument '<keyboard layout="de"/>' from the terminal configuration in order to use US-english keyboard layout instead.
