Key Press Problem

Question

Hello!
First i want to say, sorry my bad english.
I'm new here,i searched on forums and web but i don't found the solution.
I have 2 scenes:
''menu''
''level1''
And i have a ''button'' in the ''level1''. This button is needed to start the game. It has only a code, that shows/hides/changes cursor. Nothing else.
In ''menu'' i have 2 frames, the first is the ''mainmenu'', and the second is the ''levelselect'' ( where i have a button that redirects you to the scene ''level1'', it works.)
I have this code in the scene ''level1'', but it only redirects me to ''menu'', frame 1,when i click that ''button''.
But i don't know why, this thing works only when i click that button, but the 2 things are not related.
This is the script for the ''escape'' key.
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_KeyboardDownHandler);
function fl_KeyboardDownHandler(event:KeyboardEvent):void
            if(event.keyCode==27)
           gotoAndStop(1, "menu")        
          trace("escape" + event.altKey);
And this is script for the button:
( I have custom cursor that activates when i press the button, it works perfectly.
Just i need to click the button and the escape to redirect to the first scene. Dont know why.)
import flash.events.MouseEvent;
stage.addEventListener(KeyboardEvent.KEY_DOWN, fl_KeyboardDownHandler);
function fl_KeyboardDownHandler(event:KeyboardEvent):void
            if(event.keyCode==27)
           gotoAndStop(1, "menu")                                                                                           //this is the code, when i press the escape key
           dot.removeEventListener(Event.ENTER_FRAME, showcustomcursor);
           stage.removeChild(dot);
           Mouse.show();
          trace("Escape is " + event.altKey);                                                                                    //this line is only for test, so i know i pressed the ''escape''
startbutton.addEventListener(MouseEvent.CLICK, activate);                                            //personal test too, i can see the whole stuff is active
function activate(event:MouseEvent):void
          trace("Activated");
startbutton.addEventListener(MouseEvent.CLICK, showcustomcursor)
function showcustomcursor(event:MouseEvent):void
  stage.addChild(dot);
  dot.mouseEnabled = false;
  dot.addEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor);
  function fl_CustomMouseCursor(event:Event)
          dot.x = stage.mouseX;
          dot.y = stage.mouseY;
  Mouse.hide();                                                             //hides the cursor
Thank you, and sorry.
EDIT: I want to press only escape key to quit to main menu, not button+escape.

Answer 1

never nest named functions. once you unnest them, copy and past your unedited code because you showed two different keylistener functions with the same name.
function showcustomcursor(event:MouseEvent):void
  stage.addChild(dot);
  dot.mouseEnabled = false;
  dot.addEventListener(Event.ENTER_FRAME, fl_CustomMouseCursor);
Mouse.hide();
  function fl_CustomMouseCursor(event:Event)
          dot.x = stage.mouseX;
          dot.y = stage.mouseY;
