F13- F24 keys not working

[LevitateGamer]

It will press f13-f24 but windows will not receive it

[edgar-bonet]

It will press f13-f24

Then it is not an issue with this library. It's an issue with Windows, or with how it is configured to handle (or ignore) those keys.

Closing as working fine for me. I see there was an issue like this some years ago, but it was fixed by #10.

I used this thing as an accessible cross-platform way to verify keypresses:

Test sketch:

#include <Keyboard.h>

const byte enablePin = 2;
const byte LEDPin = LED_BUILTIN;

void setup() {
  pinMode(enablePin, INPUT_PULLUP);
  pinMode(LEDPin, OUTPUT);
  Keyboard.begin();
}

void loop() {
  if (digitalRead(enablePin) == LOW) {
    Keyboard.press(KEY_F16);
    digitalWrite(LEDPin, HIGH);
    delay(500);
    Keyboard.releaseAll();
    digitalWrite(LEDPin, LOW);
    delay(500);
  }
}
