hey michael. thanks heaps for the speedy reply

i do most of my modelling in maya so that's for sure the navigation scheme i'd prefer

ALT+LMB = orbit
ALT+MMB = pan
ALT+RMB = zoom

these behave ( most significant in relation to zoom ) such that you can move the mouse in any direction up down left right ( not just constrained to a left or right. up or down )

if this was offered as an option. that would be a massive win ( not having to ' rethink ' the nav when jumping in and around other apps )

you mentioned being able to edit the moi.ini file though. do you think it would be possible to replicate the maya nav EXACTLY through there ? more than happy to go down that path if it's an option ( ? )
