用karabiner来加热键

增大减小音量：

<?xml version="1.0"?>
<root>
<item>
<name>Volume Keys</name>
<appendix>Up, Down</appendix>
<identifier>remap.volumeKeys</identifier>
<autogen>--KeyToConsumer-- KeyCode::F14, ConsumerKeyCode::VOLUME_DOWN</autogen>
<autogen>--KeyToConsumer-- KeyCode::F15, ConsumerKeyCode::VOLUME_UP</autogen>
