Keyboard nav_Flash MX 2004

Question

Hello,
I've been trying to get the keyboard navigation to work with
no success. What I want is for users (especially visually impaired)
to be able to navigate using right and left buttons to progress
through a slide show using Flash MX 2004.
These are the instructions I've followed to the letter--what
am I doing wrong?!
1. Create an invisible button.
2. Place button instance on stage.
3. Select the instance and open the actions panel.
4. In the Actions panel, enter on(keyPress "<Right>"){
nextFrame();
This is from Chun and Garraffo's Macromedia Flash Advanced
book. It's not an issue of formatting since much of the script is
available from the drop-down menus in the Action script panel.
Any help would be GREATLY appreciated since I've been
struggling with this for weeks (searched many sites, tried many
other scripts, etc.).
Thanks!
Natasha

I don't know about your sample code. But, try this.
var keyListener
bject = new Object();
keyListener.onKeyUp = function() {
if(Key.getCode() == Key.RIGHT)
nextFrame();
if(Key.getCode() == Key.LEFT)
gotoAndStop(_currentframe - 1);
Key.addListener(keyListener);
