I am not sure what you mean by button back.

If you want to know when a Button is pressed, then you are best coding a FieldChangedListener for the Button. 

Let us know if this is not enough information for you.

Button back is the button with the back arrow.

If you are using the MainScreen, then you can override keyChar, and look for the ESCAPE character.  here is some sample code:

        protected boolean keyChar(char character, int status, int time) {
            // regardless of where we are, Esc will exit
            switch (character) {
                case Characters.ESCAPE:
                    close();
                    return true;
                default:
                    return super.keyChar(character, status, time);
            }
        }

Yes, this is it!
