// use this option for Windows and Linux:
// char ctrlKey = KEY_LEFT_CTRL;

// make pin 2 an input and turn on the
// pullup resistor so it goes high unless
// connected to ground:
pinMode(2, INPUT_PULLUP);
// initialize control over the keyboard:
Keyboard.begin();
}
void loop() {
while (digitalRead(2) == HIGH) {
// do nothing until pin 2 goes low
delay(500);
}
delay(1000);
// new document:
Keyboard.press(ctrlKey);
Keyboard.press('n');
delay(100);
Keyboard.releaseAll();
