... so, you need a model that can provide both the list and the selection:

<div><span style="font-family:Arial,Helvetica,sans-serif;font-size:13px">Hmm.. there is no quick way to try this out in a Workspace. We could use a dictionary-like object that reads and stores data on #doesNotUnderstand:. :-) Then you wouldn't have to implement

You need a selection for that. That's what you navigate: the selection.

I wonder how I enable the navigation keys (cursor keys plus page up / page down)<br>
