Standard Autodesk orbit - Shift+Middle Mouse Button or use the viewcube. The neon snake think is the marking menu. Do a single [right]click to see the menu, a [right]click-drag in the right pattern initiates whatever command is in that pattern (highlighted by the neon snake thingy). Think back to our marking menu conversation.

It's all fairly intuitive to an Autodesk software user. <shrug>
