Also: on any component I have

Modifier.clickable { }

and/or

Modifier.pointerInput(Unit) {
    detectTapGestures(
        onPress = {/* Called when the gesture starts */ },
        onDoubleTap = { /* Called on Double Tap */ },
        onLongPress = { /* Called on Long Press */ },
        onTap = { /* Called on Tap */ }
    )
}

how could I detect a Mouse right button click ??

This is only possible on a low level, and only in desktop target: https://github.com/JetBrains/compose-jb/tree/master/tutorials/Mouse_Events#mouse-rightmiddle-clicks-and-keyboard-modifiers

you should manual import getvalue and setvalue current
