How can I remap right ALT to right CMD in OS X?

Question

I use the Polish keyboard layout in OS X Leopard.

I'd like to remap right alt to right cmd and disable right alt.

Answer 1

KeyRemap4MacBook does have a predefined setting for changing the right command to option:

If you also want to disable the right option, you could use a private.xml like this instead:

<?xml version="1.0"?>
<root>
  <item>
    <name>test</name>
    <identifier>test</identifier>
    <autogen>__KeyToKey__ KeyCode::COMMAND_R, KeyCode::OPTION_R</autogen>
    <autogen>__KeyToKey__ KeyCode::OPTION_R, KeyCode::VK_NONE</autogen>
  </item>
</root>

See the source for the key code values and predefined settings.
