[QGIS-Developer] QGIS 3D: navigation questions

I think I heard several people stating that the navigation in QGIS 3D is 
too fast. Nyall has a PR to slow down navigation when holding the 
Ctrl-key - which unfortunately hadn't been merged to master yet.

To me the question is: when the majority of users think that navigation 
is too fast, shouldn't the default already be slower?

Other navigation issues I have:

* I did not find a way to lower or raise the altitude of the "camera" 
while staying it the same positions and not changing all the viewing 
angles (like taking the helicopter up and down at the same position). Is 
there a hidden shortcut for that?

* When rotating the whole model (middle mouse button) - how can I 
determine the rotation point? What is the rule for rotating the whole model?

Is there any documentation somewhere about how the navigation should 
work? I read something about support for keyboard (arrow keys) - but if 
I use the arrow keys, only the main 2D canvas is panned, not the 3D 
view. Also the Shift key, which should be used according to 
has no effect on my machine - maybe another KDE/Plasma issue?

Thanks for your reply.
