Show actual postion in Navigator (Outline)

Hi

I have the following problem:

I have a frameset with a navigator outline on the left. The entries link to documents which are then shown in the right frame.

In these documents are links to other documents.

Now when I click on one of those links in a document I want the following to happen:

  1. Linked document opens in the right frame (which is no problem and already works)

  2. Navigator on the left jumps to this document link and the link is highlighted (for which I have no idea)

Thanks for any idea (also hints to third party tools, navigator applets which can do this etc.)
