Pan and Selected Zoom

[Codesmith]

It may be I missed these tools in the EA interface, but I miss them nevertheless.

In a diagram I should be able to grab the screen and "Pan" or move the diagram with the mouse instead of moving each of the scroll bars.  Like the "Hand" in Acrobat.

Also when I have something selected it should be obvious to the system that that entity or area is what I am interested in. So the system should Zoom to selected object or area.  and it wouldn't hurt to have these tools accessable in the context menu

This may help to avoid using the scroll bars.  
- Click on a diagram to give it focus
- Hold the control key down
- Use the wheel on your mouse to scroll in or out of the diagram to get the level of detail you want.
