Using Ensime + SBT to browse scala library

Question

Is it possible to use Ensime and SBT to go to the definition of Scala library classes?

I know it is possible to see the definition of elements (using M-. or Control+Left-Click) and from there it's possible to see the doc page. Is there any way to tie this functionality into src as well?

UPDATE:

my project config (.ensime file):

(
  :root-dir "/Users/eugene/tmp/scrap"
  :sources (
    "/Users/eugene/tmp/scrap"
  )
  :reference-source-roots (
    "/usr/local/Cellar/scala/2.9.2/libexec/src"
  )
 :compile-deps (
    ""
  )
  :target "/Users/eugene/tmp/scrap"
)

/usr/local/Cellar/scala/2.9.2/libexec/src contains:

scala-compiler-src.jar scala-library-src.jar  scala-swing-src.jar
scala-dbc-src.jar      scala-partest-src.jar  scalap-src.jar

build.sbt:

name := "scrap"

version := "0.1-SNAPSHOT"

scalaVersion := "2.9.2"

Download the sources of scala-library and then set :reference-source-roots in your project config file.
