Is it possible to catch the onKeyDown event on a page that includes a Java applet?

I have a webpage containing a frame that has a java-applet inside of it.

On the webpage I check for onKeyDown. It works fine.

Except when the (i)frame contains a java-applet. Then it seems like the java-applet is steeling the event from the webpage, but unfortunately in a way, so that the user can still press [backspace] on the webpage and the browser goes 1 page back in the history.
The problem is that my OnKeyDown event doesnt catch the [backspace] (when the java-applet steels it). The whole idea was to prevent the user from being able to hit the [backspace]. And its working fine when there is no java-applet on the page.

What should I do in order to also catch the [backspace] when the page contains a frame with a java-applet?

Redesign the application so it can handle going back.

For example on the previous page have

<a href="page2.html" onClick="location.replace(this.href); return false">Next</a>

I guess You mean CANT'T ? :)

But I dont have a link or a user clicking on something, so I cant use Your suggested solution.
Its event driven, so its the application itself that changes the content of the frame - and sometimes its a java-applet.

But isnt there a way to catch it?
