Version 44 Code with CTRL-ALT E

John Saltsman updated the example to work with the OSv44 log-in screen as well as adding in the CTRL+ALT+E since that is the step some people miss most often : 

/*  A few reminders
   - ever statment in C needs to end in an semicolon otherwise you will get an error
   - make sure you go into tools>USB Type> and then select keyboard+mouse+joystick otherwise you'll get the error "keyboard not reconized"
   - this https://www.pjrc.com/teensy/td_keyboard.html and this https://www.arduino.cc/en/Reference/HomePage are helpful

void setup() { //this loop will run once
  //gives the computer time to reconize the device 
  delay(4000); // it times in miliseconds
}
void loop(){//this loop will keep repeating

Keyboard.set_modifier(MODIFIERKEY_CTRL); // press and hold CTRL
Keyboard.send_now();

Keyboard.set_modifier(MODIFIERKEY_CTRL | MODIFIERKEY_ALT); // press ALT while still holding CTRL
Keyboard.send_now();

Keyboard.set_key1(KEY_E); // press E, while CLTR and ALT still held
Keyboard.send_now();

Keyboard.set_modifier(0); // release all the keys at the same instant
Keyboard.set_key1(0);

Keyboard.send_now();
