| Input | Does |
|---|---|
| Left-drag | Orbit around the target |
| Wheel | Zoom |
| Middle-drag | Pan — keeps working while an annotation tool is armed |
| F | Frame the selection |
| M / A | The ruler / the angle — press again to put it away |
| O | Orthographic ↔ perspective |
| ViewCube | Click a face for an axis view, an edge for 45°, a corner for isometric |
| PERSP / ISO | The plate under the cube: the projection (ISO being the orthographic one), the same switch as O. It moves no camera — the cube above it is what aims the view |
