How to disable CMD + E to eject? I have a MacBook Air, I want to disable the CMD+E keyboard shortcut to eject because I want to assign it to another application and I really don't need to eject anything as I don't have a CD drive.

I've searched in the keyboard preference but that shortcut is not there.

Any ideas?
You can use Karabiner with a private.xml such as this:

&lt;?xml version="1.0"?&gt;
&lt;root&gt;
  &lt;item&gt;
    &lt;name&gt;Disable ⌘E&lt;/name&gt;
    &lt;identifier&gt;DisableCMDE&lt;/identifier&gt;
    &lt;autogen&gt;
      __KeyToKey__
      KeyCode::E, VK_COMMAND | ModifierFlag::NONE,
      KeyCode::VK_NONE
    &lt;/autogen&gt;
  &lt;/item&gt;
&lt;/root&gt;
