The Basics

Every stream has two basic parts

data-in - A chunk or EOF enters the stream
data-out - A chunk or EOF leaves the stream

I'm combining both "data" and "end" events since "end" is just a special data packet signifying the end of the stream.

Flow Control

Go to Sublime Text 2 > Preferences > Key Bindings - User and add this JSON to the file:

[
    { "keys": ["super+shift+l"],
      "command": "insert_snippet",
      "args": {
        "contents": "console.log(${1:}$SELECTION);${0}"
      }
 }
