First Im a really noob for programming. I have this code and working fine. Digital pins all ok but someone can do help to add remaining analog ports to work like A3? Arduino Pro Micro A0, A1, A2 pins are remaining..
No need shorter code or better code!
Thank you!

Your method would work fine except it is I/O intensive. Without a schematic it appears each button is using a port pin. Try searching for "arduino keyboard example" there are a lot of them available. Since I have had the same problem I many times will use a keyboard encoder chip.
Hey, I tried everything based on my knowledge (noob level) but I can't success. Here are the affected lines of code. I have commented which lines need help.
const int BUTTON_PIN = A3;
const int BUTTON_PIN2 = A2; // added A2, A1, A0 pins
const int BUTTON_PIN3 = A1;
const int BUTTON_PIN4 = A0;
#define BUTTON_KEY 'm'
#define BUTTON_KEY2 'l' // added wich characters need to print
#define BUTTON_KEY3 'n'
#define BUTTON_KEY4 'o'
void setup() {
Serial.begin(115200);
Keyboard.begin();
Button.attach(BUTTON_PIN, INPUT_PULLUP); // Need help for here to extend code wich BUTTON_PIN activated now only one pin work
Button.update();
if (Button.fell()) {
Keyboard.press(BUTTON_KEY); // Need help for here to extend code wich defined BUTTON_KEY print ony one character can be print
}
if (Button.rose()) {
Keyboard.release(BUTTON_KEY); // Need help for here too
}
Please show the full sketch, even if you change only a comma.
If you leave parts of the code out, then those are the parts that are the most of interest to us

This is the Bounce2 example for two buttons: bounceTwo.ino
This is the Bounce2 example for many buttons: bounceMore.ino
The example uses a pointer and a 'new' keyword. That was probably easier to initialize the objects. I suggest you copy that. Put a link to the example in comments in your sketch.
What you do in setup with Bounce() might also work. I have not tested it.
Do you see in "bounceMore.ino" how all the buttons are initialized in setup() and all the buttons are checked in the loop() ? That is exactly what you need.
Connect the Button.fell() to Keyboard.press() and the Button.rose() to Keyboard.release() for all the buttons in the for-loop.
