Navigation — as in USD Composer

Alt + LMB: Orbit around the point of interest
MMB drag: Pan; the point of interest moves with you
RMB drag: Look around from where you stand
Wheel: Dolly toward or away from the point of interest
Alt + RMB: Dolly by dragging, for fine control
F: Frame the selection — the whole stage if nothing is selected
Shift + drag: Slower, while orbiting, panning or dollying

Manipulate

Q W R S: Select · Move · Rotate · Scale (E also rotates — Composer's own binding is W E R)
Drag a handle: Along one axis; the flat square moves in a plane
Drag the prim: With Move active, dragging the prim itself slides it along the ground
Ctrl: Hold while dragging to invert the snap setting
X: Toggle local and world space

Prims

This is a simulation, not a USD runtime: it models layers, strength ordering, def and over specs, opinion resolution, muting and deactivation. References, payloads, variants and time samples are deliberately left out — Chapters 3 and 4 of First Steps in OpenUSD cover the composition arcs properly. Nothing here talks to a server; the stage lives in this tab.
