Do you want to use alternate functions using the Numlock key (like the modifier keys) ? @riorivaldi13

Try pressing 0xdb.

This issue has been fixed on 2021-11-29 (PR #57). Using the master branch, you can now

Keyboard.write(KEY_NUM_LOCK);

Note that the feature is not yet available in a released version of the library.

Closing as resolved by #57

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.write(KEY_NUM_LOCK);
    digitalWrite(LEDPin, HIGH);
    delay(500);
    digitalWrite(LEDPin, LOW);
    delay(500);
  }
}
