The other day I sat down at a fellow students Vectorworks stations I discovered I couldn't do a thing without my workspace. I had no idea where menu items were or how to edit or change modes. If I had taken a test, you would conclude I know very little about Vectorworks and would not be productive.
I would do really well on the keyboard count productivity scale on my system. Everything I do is left handed keystokes and right handed mouse buttons, wheels, and moves.
