You can cycle between viewports using Ctrl+Tab and Ctrl+Shift+Tab or ViewportTabs, you can also switch viewports using Ctrl+F1,Ctrl+F2,Ctrl+F3,Ctrl+F4.
You need to first change the viewport projection to Perspective.
when I did the SetCiew Cplane Left it did exactly what I wanted it to do. like i mentioned about the 3ds max thing! If went to the left view and I was still in perspective. that’s what I want!
can I somehow make that command happen by just typing L for left and r for right and t for top etc??
The Keyboard options manage keyboard shortcuts to run Rhino commands or scripts. However, you can only set macro for predefined available key combinations.
