Z's key commands are most effective. Rees did stop posting here some time ago. I find this forum important to keep acquainted with the subtle points, so easy to miss and forget. Thanks to all the bright posts and Zweb. My difficulty is navigating while in perspective.
Axonometric navigation works spendidly and fullfills most needs.
Key commands with old, pre 3.0 navigation speeds up many maneuvers. To get smoothly operational, perspective rotating views, i need to use views which were saved before hand. My thoughts I too find Z's navigation tools adequate. I agree with Bo that navigating while in perspective can be cumbersome. So, in my opinion, users would be better served to learn how to use the good navigation tools Z provides than to concern themselves with what it doesn't do.
