Modify Expose button on my macbook for another shortcut? The F3 button on my rMBP has a figure which shows 3 rectangles, pressing the button without the FN key initiates the Expose function. I want to modify that key for another function. However I cannot directly modify it via preferences because pressing that button does not register as a specific keyboard shortcut.
You could also change it to a normal F-key with FunctionFlip.



If anyone else is looking for a way to change it with KeyRemap4MacBook, just create a private.xml like this:

&lt;?xml version="1.0"?&gt;
&lt;root&gt;
&lt;item&gt;
&lt;name&gt;test&lt;/name&gt;
&lt;identifier&gt;test&lt;/identifier&gt;
&lt;autogen&gt;--KeyToKey-- KeyCode::EXPOSE_ALL, KeyCode::F19&lt;/autogen&gt;
&lt;/item&gt;
&lt;/root&gt;


The keycode constants are defined in src/bridge/generator/keycode/data. The test folder has a checkbox.xml with all the predefined mappings.
