Switching Viewports in AutoCAD Architecture or ADT

It's funny the things we take for granted. Being a long-time (R11) AutoCAD user, I have habits of things I have done in AutoCAD and take for granted that I can do them in ADT. After all, it is based on AutoCAD.

One thing that often bothers users is the Draw toolbar in AutoCAD is different than the Shapes toolbar in ADT. The construction line act differently between those too.

Here's another example of a difference. Try switching between viewports. Yes, you can double click a viewport in paperspace and go through the viewport. Yes, you can use the maximize viewport button to get into the viewport very effectively. But do you remember using Ctrl + R to switch between viewports? This is especially helpful if you have a viewport within a viewport. Well, if you have ADT 2007 or AutoCAD Architecture 2008, at least you will know you are not crazy. I finally broke down and asked Autodesk support about this since I could not find anything in the knowledgebase or discussion groups or forums.

As it turns out, there is a knowledgebase document (knowledgebase isn't known as the easiest to search) that cover this. The solution is only listed for 2007, but I'm told this affects 2008 as well. You'll need to edit the .cui to get the shortcut.
