Send key strokes via serial.write

i trying send ctrl+k keystroke through serial write computer.  having troubles finding correct hex, ascii, or decimal this.  compiler error when working way.  understand not leonardo or flash dfu arduino.

i have sent space command.  using additional program acc keys capture serial data.

ide arduino 1.0.6
using arduino: 1 week 

i appreciate either proper search topic or code.  have spent 2 days looking key command without sending scanner or lcd display.


i don't understand error , warning yet.  sorry if has been asked already. 

thank help.

my code

code: [select]

// function changecolor send keystroke 'ctrl+k' computer
void changecolor () {
  int keycommand[] = {0};
  keycommand[0] = 11;
  serial.write(keycommand, 8);
}

error

code: [select]
