## Karabiner: a keymapping tool for osx

I have found a wonder tool for remapping keys on osx: Karabiner - Software for OS X

User manual: Karabiner - Software for OS X

User's keymap settings are stored in a file called private.xml, it can opened like this:

Note that there is also a "Event Viewer" in which you can look up keycodes and app identifiers in action.

After browsing through the documentation I have come up with a xml configuration specifically effective for Eclipse text editor area:

<?xml version="1.0"?>
<root>
<appdef>
<appname>ECLIPSE</appname>
<equal>org.eclipse.platform.ide</equal>
</appdef>
<item>
<name>Esc to ctrl-bracket three times in Eclipse</name>
<identifier>private.esc.to.c.bracket.three.times.eclipse</identifier>
<only>ECLIPSE</only>
<uielementrole_not>AXTextArea</uielementrole_not>
<autogen>
__KeyToKey__
KeyCode::ESCAPE,
KeyCode::BRACKET_LEFT, ModifierFlag::CONTROL_L, KeyCode::BRACKET_LEFT, ModifierFlag::CONTROL_L, KeyCode::BRACKET_LEFT, ModifierFlag::CONTROL_L
</autogen>
</item>
</root>


Since I use vim mode (vrapper plugin), I use the Esc key a lot, so I mapped Esc to its equivalent ctrl-[ repeated three times.

This is indeed a extraordinary piece of software, I will definitely learn more about it later!
