Define the pins on the Arduino that will be used for TX and RX in the Software Serial library, and connected to the Bluefruit EZ-KEY.

// CONFIGURATION
/*---------------------------------------------------------------------------*/
#define RX_PIN 10
#define TX_PIN 11
Basically, for each of the 12 inputs you can specify a modifier (SHIFT, CTRL, ALT, etc.) plus up to 6 keycodes which will be sent out (with a Keys-Down) via Bluetooth. When the input is released, a matching Keys-Up message is sent.
To customize, you simply need to specify an input (0-11) and then a modifier (8 available choices) and then up to 6 keycodes (about 112 options available, such as ARROW UP or “k” or numeric keypad minus).
See the original article for a walk-through.
Hopefully the user interface will be self-explanatory.
