ark documentation and extraction issues

[Burkhard Lück]

Hi,

trunk kdelibs/kdeutils from 20090106

In the ark documentation I read:
<sect1 id="ark-work-files">
<title>Working with Files</title> says:
<guimenuitem>Preview</guimenuitem> will open the file in the integrated 
viewer.

The <guimenu>Action</guimenu> Menu says:
<guimenuitem>Preview</guimenuitem>
<action>Opens the currently selected file in the associated viewer
program.

What is correct, integrated or associated viewer?

In menu Action->Extract... (Ctrl+E) I have an item "Quick extract to...", but 
this is always disabled. How to enable it? What does it do?
Only Ctrl+E or click on Extract in the toolbar opens the Extract dialog.

The additional menu items in this submenu are from [DirSelect Dialog] Histrory 
Items in .kde/share/config?
