title: ST2 Keymap: Args for "expand_selection"
body: <p>Does anyone know how to edit the "expand_selection" keymap in Sublime Text 2 so that it only selects the current line and not the line break that follows it?</p>
  
  <p>The default keymap is this:</p>
  
  <p>{ "keys": ["ctrl+l"], "command": "expand_selection", "args": {"to": "line"} }</p>
  
  <p>The problem is that when you select the line and begin replacing it with new code, the line that follows it moves up to the current line.</p>
  
  <p>I assume you replace "line" in the "args" section with something else, but I can't seem to find this documented anywhere.</p>
