How to map Option+X but not change Option+Shift+X in KeyRemap4Macbook? I want to map Option+X to something. But this mapping effects Option+Shift+X key binding as a side effect. Is there a way to prevent it?

Here is an example mapping that I use:

&lt;item&gt;
    &lt;name&gt;movement home&lt;/name&gt;
    &lt;identifier&gt;private.movehome&lt;/identifier&gt;
    &lt;not&gt;VIRTUALMACHINE&lt;/not&gt;
    &lt;autogen&gt;
        --KeyToKey--
        KeyCode::C,ModifierFlag::OPTION_L,
        KeyCode::CURSOR_LEFT,ModifierFlag::FN
    &lt;/autogen&gt;
&lt;/item&gt;
&lt;autogen&gt;
  __KeyToKey__
  KeyCode::C, VK_OPTION | ModifierFlag::NONE,
  KeyCode::CURSOR_LEFT, ModifierFlag::FN
&lt;/autogen&gt;


The use of | ModifierFlag::NONE prevents other key combinations from being remapped.
