A comment on the original request:
Remapping of Camera manipulation has far greater consequences than maybe immediately obvious. The popular Maya scheme for instance, which heavily relies on the ALT key would conflict heavily with Rhino’s concept of action inversion, duplicate dropping, certain selection methods, interactive change of Camera Focal Lenghth, I’m sure I still forgot something. To hook up such a change properly one had to allow users to relocate all default ALT functionality to another modifier key, which isn’t easy, as any of these already already have a lot other functions too – one might want to relocate these as well. Unfortunately the great majority of programs I know which allow for alternative navigation schemes offer no solution for this problems, resulting in a loss of functionality – a tiny single purpose tool such as Balancer may be the exception.
The only 3D program I know which allows for remapping every keyboard and input device event causes considerable customization effort, this by far is not for everyone.
