/**
 * special_functions - intercept keyboard commands before they get sent
 *
 * Used to:
 *
 * 1) reconfigure the keyboard and clear any stuck modifiers
 * 2) Reset BLE on Ctrl-Shift-Esc
 * 3) Send media key commands
 *
 * Could be modified to do whatever you would like...
 *
 * Possibly convert the keypad into a T9 keyboard
 *
 * Return a 1 to send the key and a 0 to block it from being sent
