Using Arduino like a keyboard

Hi I have DUE
And I'm trying to make this guide
https://www.arduino.cc/en/Tutorial/KeyboardAndMouseControl
But he writes me an error message that I lacked
Keyboard.h Library

sketch_oct08b.ino:23:22: fatal error: Keyboard.h: No such file or directory
compilation terminated.
Error compiling.

I downloaded the latest version ..

HELP

Did you #include keyboard.h at the top of your code?

Do you have the library in the directory the compiler is expecting to see it? - look at the error message - it'll tell you where the compiler is looking for the file.

Is the library one that needs to be installed via Sketch/Include Libraries?

Did you close and reopen the IDE after adding it?

yes I #include keyboard.h at the top of code

in C:\Program Files (x86)\Arduino\libraries

I do not have a directory called "keyboard"
It might be the reason?
Where can I download it?

Google is your friend. Try "Arduino keyboard.h" and see what happens.

I tried I could not find anything

its called KeyboardController.h

The example has been updated prematurely.
Keyboard and Mouse will be separate libraries in IDE version 1.6.6.
Just remove/comment the #includes until 1.6.6 is released (or get an hourly build).
