-// This software implements an Sony Vaio VPCCW Laptop Keyboard Controller using a Teensy LC on

-// This routine uses the Teensyduino "Micro-Manager Method" to send Normal and Modifier 
-// keys over USB. Multi-media keys are are sent with keyboard press and release functions.
-// Description of Teensyduino keyboard functions is at www.pjrc.com/teensy/td_keyboard.html
