3DConnexion Navigator - and Viewport question

I’d like to set up my Space Navigator to have the left button go back to the 4View as if I’d clicked the icon on the toolbar.

When I try to use ‘4View’ for the command string, it says the command isn’t implemented.

I’d like to have tilt, but I need to have a quick way to reset the views to Top, Front, Right, etc.

What would even be better is to have a lock for all but the Perspective view so the three don’t tilt unless I want them to.

Aha. ‘Plan’ works great.
