I think you exagarate a bit the fact that you need to push the alt down (rember the moving commands ara all combination of mouse and alt). Come on its just 1 button fo gods sake. THen you can use the mouse for all that.
Its funny this must be the first thread ever that says the mayas panning zooming rotating sucks... Actualy usualy people tell otherway around...
And no the rhino interface isnt much better than anything else.
besides the maya interface is such that youd be keeping your other hand around alt shif controll anyways... wich leads you intuitively close to following shortcuts
undo (cntr-Z), redo (shift-Z), gridsanp (x), curvesnap ©, vertexsnap (ctrl-v), Focus all (a), set keys (s), display quality mm (d), foucus selected (f), repeat last command (g), the tools (qwerty), shading modes (12345).... + A lot of modifered versions.
Then for the shift controll them selves (modifers are locked). shift forces toggle selection, and controll subtract selection, shift controll add slelection. Alt is reserved for camera manipulation and it overrides everything!
Then theres plain mouse wich houses case sensitive object marking menu right button. Modify selected value Middle mouse. And manipulate right mouse.
I considered locking this therad but anyone is free to dislike maya, so... Maya by the way is just like a woman if you dislike her she will dislike you back!
