Remapping Y and Z keys with Karabiner I just want to switch the Y and Z keys. I've tried everything with Karabiner on High Sierra, but it just doesn't seem to work. I always get an error message along the lines of: "Karabiner Error. Error in xml. Unknown symbol: KeyCode::0x6"

Attached you can see the code that I've been trying to use, as well as the modifier keys for Y and Z (which I've tried every variation of in the code). 

   &lt;root&gt;
      &lt;item&gt;
      &lt;name&gt;Swap Space and Tab&lt;/name&gt;
      &lt;identifier&gt;private.swap_z_and_y&lt;/identifier&gt;
      &lt;autogen&gt;__KeyToKey__ KeyCode::0x6, KeyCode::0x10&lt;/autogen&gt;
      &lt;autogen&gt;__KeyToKey__ KeyCode::0x10, KeyCode::0x6&lt;/autogen&gt;
      strong text&lt;/item&gt;
   &lt;/root&gt;


Please help!
ahem … Karabiner 10.xx no longer works with MacOS (High) Sierra …

The interim app Karabiner Elements 12.10 will solve your problem very easily, but "Complex Modifications" –meaning modifier/key combinations or e.g. "if_held_down"– can locally only be added/modified by manually editing      ~/.config/karabiner/karabiner.json.
