This is the error message I get.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Even though I have included the keyboard library at the top it doesn't seem to be successfully including. I get the same error message without the "#include <Keyboard.h>

Oops, here is the code for my remote.

#include <Keyboard.h>



#include <IRremote.h>
#include <IRremoteInt.h>



int RECV_PIN = 11;

IRrecv irrecv(RECV_PIN);

decode_results results;
int key_pressed;
int last_key_pressed;

void setup()
{

  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
  Keyboard.begin();

}

void loop() {

//Stuff to read the TV remote
  if (irrecv.decode(&results)) {
    key_pressed = results.value;
    Serial.println(key_pressed);
    irrecv.resume(); // Receive the next value
  }

  if (key_pressed == last_key_pressed) key_pressed = 0; //I only want to check one time, what key was pressed

  if (key_pressed == 0x5743B44B) { //Change this number according to the keys that you want to use in your remote
    Keyboard.press(KEY_RIGHT_ARROW);
    Keyboard.releaseAll();

  }

  if (key_pressed == 0x57437887) {//Change this number according to the keys that you want to use in your remote
`    Keyboard.press(KEY_LEFT_ARROW );
    Keyboard.releaseAll();

  }

  last_key_pressed = key_pressed;

}

Thanks, I just read about the Keyboard Library. Luckily my Uno was my experimentation board and I had yet to order the actual board for the project. Going to order a micro and I get back to this thread, once it arrives, if it works or not.

Got the micro. Library works fine now. Thanks.
