I want AvalonEdit to be a text viewer.

I can make:

```
textEditor.IsReadOnly = true;

```

and the control does not allow to make any changes, but it still behave like an editor - shows a caret, and using navigation keys (arrows, page up/down) moves the caret instead of scrolling the view.

Is there any way to make it a viewer? Or at least, hide the caret?
