Go to your Documents\ArcaniA - Gothic 4 folder. In this folder there is Input.xml file. Open with notepad or wordpad. Paste these lines After the word <Input>
When in game, press Left CTRL+Q to go in to the fly mode, press and hold jump and move around the map. Click on Escape/Esc to portal to that location. It is very good cheat to save time.
Also with that code, if you press left Shift, you can sprint/run faster. Saves time running through dungeons.

Should look like

<Input command="sprint" set="1" >
<Key name="shift left"/>
<Activation type="active"/>
</Input>

<Input command="sprint" >
