LIBGDX: What is the meaning of the return value of InputAdapter keyDown, keyUp ... etc.

Question

I'm having problems processing input from several separate InputAdapters that use keyDown / keyUp.

Gdx.input.setInputProcessor( new InputMultiplexer( keyboardController1, keyboardController2, keyboardController3));

Only the first in the line works, while the others do not; in this case keyboardController1. I guess this has something to do return true;with the end of the methods keyDown(). I tried reading documentation, tutorials, posts ... etc. But I still can not understand what the return value means and what, and to what logical values ​​I should set it. My question is: What is the meaning of the boolean return value of keyDown / keyUp (etc.)?

switch(keyCode) {
case Keys.W:
     // Handle the event for "W" key pressed
case Keys.A:
     // Handle the event for "A" key pressed
// Other cases
default:
     return false;
}
return true;
