Camera: fly or orbit (View > Camera, Shift+C, kept): orbiting turns round what you look at on a right drag and the wheel zooms; the hints follow it; the site's 0.8 (getting round, smoother); fry_where for trying it

how fast it all goes. Alt + right drag orbits round what's picked; middle drag pans. Rather
orbit, as in Blender? **Shift+C** (or View > Camera) switches: right drag turns round what you
look at and the wheel zooms.
- **Solid** view for modelling, **Rendered** with a real sky, sun and soft shadows (Z). Wireframe
(Shift+Z), X-ray (Alt+Z). The Render tab: the sun, sky, ground, brightness, shadows, glow;
F12 saves a picture of just the view.
