The dashboard is fully keyboard-driven. Global keys work from any panel; the rest are scoped to the focused panel. The help overlay (?) shows the same reference in-app.
Each panel's title carries a bold-cyan [N] badge that mirrors the number key for that panel: [1] Safety, [2] Commands, [3] Joints, [4] Events, [5] Parameters.
Visualization tab
The Visualization tab renders the live robot in 3D from its URDF topology and joint positions. The camera orbits the robot and reposes in real time as sensor data arrives.

Enum-typed args ({:in, [...]} in the Spark schema) render as ‹ value › chevrons and respond to ←/→ (or h/l) instead of needing the atom typed literally. For non-enum args, h/l continue to append to the buffer; ←/→ are no-ops outside of enum picks. Values are parsed before dispatch: "true"/"false" become booleans, ":foo" an atom, numeric an integer or float, otherwise a string.

Cycle to the next bridge tab (Local → bridges → Local)
Step size is 1% of the declared range when min / max are known — the Spark schema's {:float, min: 0.0, max: 1.0} form on the Local tab, or the bridge's flat :min / :max keys on a bridge tab — and the new value is clamped to the bounds. Parameters without bounds use an absolute step of +1 for integers and +0.1 for floats. The same keys dispatch through BB.Parameter.set on the Local tab and BB.Parameter.set_remote on a bridge tab; a successful remote set refetches that bridge's parameter list so the cached values stay in sync.
