title: Atom Editor Keyboard Shortcut for Split Selections into Lines
body: <p>In the Atom editor the default behavior for <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>L</kbd> is to <em>select-grammar</em>. I have successfully changed this to <em>split-selections-into-lines</em>. How do I now assign <em>select-grammar</em> to <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>J</kbd>? </p>
  
  <p>I put the following in my keymap.cson file and <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>L</kbd> is working, but <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>J</kbd> does nothing at this point.</p>
  
  <pre><code>'atom-text-editor':
    'ctrl-shift-L': 'editor:split-selections-into-lines'
    'ctrl-shift-J': 'editor:select-grammar'
  </code></pre>
